Mine does, but as I said, his lowest setting was too strong IMO compared to what I can do with syringe with 4 openings. And I’m not inclined to do it under pressure, eg I don’t want to break the wax from the walls with water, I just want to flush already loose one. At least that’s my reasoning. I didn’t need to use that special syringe either. But I have all equipment now in case it ever repeats. 
I’ve used all the methods you list too. Any of them can benefit from warming the liquid.

I held my oil (in small 5ml squeeze bottle, I have bunch of those, never used, from my play with aromatherapy) in my hands for like half an hour before pouring in my ear
I also dry my ears with a hairdryer instead of the qtip.
I cannot stand the airflow, too loud, too annoying, and too much airflow 
I don’t use it on my hair unless I need it immediately dry (which happened like maybe 5 times in last two decades), and then I put ear plugs in my ear while doing so. Ok, granted, we do have some beast of a hairdryer which needs like less than a minute to dry classic men short haircut that’s overgrown, so, 2-3" of hair length and lot of it (we both wear similar, me having even shorter hair, but I haven’t used dryer even when I had 1m long hair, that’s what, around 40").
The peroxide can irritate as it’s pretty strong stuff.
Yup, that’s good warning!
Especially I wouldn’t recommend it for weekly/daily use, but more like a day/two when solving acute problem, and only if you don’t have sensitive skin nor wounds/scratches of any sort.
What’s funny is that if wax can be moved in home, all solutions have same efficiency, those above vs ‘special over the counter drops’. In some cases they even proved that doing nothing is similarly effective, since our hairs inside the canal are moving it out when we chew and move jaw anyway.
And if wax is dry, really stuck, then your best bet is the expert, since with anything you shove down there you risk injury.
And after that you can use any of the above for maintenance, eg once a week or so, in order to not come to the point where your hair cannot move that out alone.
