Uf, you’ve just confirmed what I’ve suspected - that finding a good fitter here will be hard. And that prices are crazy 
I’ve moved last year to CH, and my ears didn’t yet come to the table, but my old fitting still works ok (I still haven’t unpacked nor find my Noah (NLW)).
To answer you ‘how to find a good fitter’ - I plan to be painfully insistent on precise answers when I decide to look for someone. Good list of things to check if they do/how they do it/to explain themselves why they’re not doing something that’s best practice and how they work around it - dr Cliff website has great list.
When someone tells you that REM machine is obsolete and that HA sw is the best, just get out and spare yourself wasted time on that initial fit - REM based speech mapping with small adjustments will and should leave you with proper program that works in quiet (and no hard environment, yours is really hard environment). That saves you tons of stupid visits of ‘how do you hear me now’ and can start working on really needed adjustments for hard environments, additional programs and so on.
For illustration, my first aids, I’ve spend 2-3 times a week for 5 weeks fo ‘how do you hear me now’ with a guy who knows sounds but doesn’t have proper equipment and we made it best possible (widex dream - phonak sounded horrible). And I’ve tried 4 more fitters/audiologists and they were shit. In Croatia. Then I moved to Berlin, went with one with really good reviews, and asked for recheck of those widexes, and he did such a mess that I’ve heard better without his programming. I asked him to reload my old programming. Also he did try to sell me phonaks with similar approach. I think it took me 2 months if not more all together and I was pissed off and decided I’ll just do DIY. Day before ordering on ebay I’ve found a fitter who does REM based fittings and follows most of best practices (some aren’t covered by insurance, so he doesn’t have equipment/sw, nor german version of such things really exist - specifically sentence in noise, but also other noise sources than whitenoise for WRS-like testing of fitting - and 90% of his clients are happy and go with basic models anyway which is 100% covered by insurance)
Yes, I wasn’t the most pleasant customer when I showed on his door so frustrated, but in just a few minutes I realised I’ve finally found someone who knows what he’s doing Not to mention that I was with 3 ENTs I think in Berlin and no one did proper audiogram. My fitter (and everyone in Croatia for that matter, so 20ish people) has no problem to do the test properly. I mean - to some I’ve told they’re doing it wrong and told what’s missing and they dismissed it. So yeah. Fun fun. I hope here folks know how to do that properly, but we’ll see.
Also, he fitted cheapest model on me for fun - so I back to back tested Marvels 90, Paradises 90 and some unitron basic model. In same quiet, listening through TV the same youtube video and same sentence over and over again - all were exactly the same. Such comparison of bunch of models is possible IMO only if someone does fast fitting, which is another huge benefit if you need that.
Anyhow, arm yourself with right questions, go here: https://hearingup.com/ click on top right on resouces and pick ‘best practices checklist’. I did this with my chosen fitter and we discussed a lot of things.
So my plan B when moving here was my fitter in Berlin who said I can come whenever.
I have intention to look here for someone good - for me that means REM based fittings, and working together with me (so I intend to keep DIY). However, I don’t need that unless something serious happens, or I decide to change my aids, which I assume won’t happen that soon (since I hate daily rechargables and it seems we’re stuck with that 
).
I might be more inclined to go to mediocre fitters (those with only ‘how do you hear me now’ method I despise) for things like ordering new receivers, and such. Maaaybe molds.
Not to mention that Berlin prices are lower than Swiss ones, so it won’t be hard to decide to get on nightjet and go to Berlin and back.
Also, shipping to CH isn’t THAT big problem - if I remember correctly, train ticket to some village in Germany from my village here will cost me around 25 chf (with halbtax, roundtrip), and there are bunch of packstation type shops which receive your package and you pick it up later. I’m using German side since that’s closer to ZH canton, more specifically https://lieferadresse-jestetten.ch/
And then you just cross the border regulary. Yes, you report for tax purposes if you go above zoll allowance (there’s an app for it), and yes you usually can’t deduct DE tax, but hell, prices are still significantly better
About your environment, I’d suggest you sit down your partner and seriously explain issues. Ideally if you can find some sound examples how it EXACTLY sounds to you. Most of partners have no idea how things are irritating when you have hear loss. Because it’s usually not exactly flat loss (as they imagine, that we hear everything worse, so we need just louder, so ear plugs are poor representation usually), but we perceive different sounds totally differently amplified eg shoe on wooden floor can drive us nuts but we won’t hear bird or alarm until it’s crazy loud.
It’s hard to explain and hard to understand. They’ll have to trust you and take you seriously. Assuming they care about you.
If they don’t, keep in mind that Aestetics should NOT be more important than you being comfortable in your own home. Take your ground there. Be it separate on different floors as a living solution or hell even divorce - because why would you want to live with someone who doesn’t want you to be comfortable in own home?
You can’t work out good middle solution if someone doesn’t care about you.
However, if they do care, there are options.
Rugs can be put on walls or ceilings and couches. Bookcases with books of uneven sizes and not perfectly flat. Small furniture to break the lines. Plants.
Also there are bunch of acoustic panels that can be bought or build to help with reducing echo.
If my partner wouldn’t want to put me in front of aestetic no matter what solution I try to find, they wouldn’t be my life partner. I don’t want to live miserable life in my own home. But I grow up to become more ‘militant’ in my approach, because after all, I live only once, and I definitely don’t want to feel bad in a place that I should call my home.
But let’s hope it’s not that dire and it’s just about person not realising how bad thing is. You don’t have to find a perfect example, you just need to find a similarly annoying example - my wild guess would be that if you grab a pan/pot and a spoon and start smashing it while talking to the person, will be more than enough to illustrate how difficult environment becomes. Put your HAs on mute during this experiment 
Also, in phonak target there are some sound examples to share on speakers to show the partner what is the issue, if I remember correctly, no clue how they work exactly, but look around, no HA needed for that.
