At least Mlem, the app for iOS is explicitly compatible to all accessibility functions in iOS. They wrote in their latest changelog that they have someone auditing their app to be compatible with this stuff.
There is the Sovol SV07 for about 300€-ish. It comes with Klipper and should check all your boxes. I bought the SV06 Plus two months ago it works OK. You have to tighten all the screws and actually read the manual, but that's it. If you want a guaranteed problem free OOTB experience, you have to buy Prusa (top quality control and software) or Bambulab (not really hackable but runs well) for 600-800€.

For me, the X270 ist the sweet spot: it is small and portable and has a acceptable battery( in fact 2 of them). The display is usable and comes in full HD. 720p is a little bit too low for my tastes. You can upgrade the RAM and put an m.2 ssd inside(although only with 2x PCIe bandwidth). You can also charge it with USB-C. With an i5 it goes for around 200€ in Germany. US prices are usually lower.
