I think Apple gets too much of a pass for being serious and commited, where other players have actual results.
On mild level accessibility, the part that surprised me the most was keyboard mapping. While macos got caps lock/esc/ctl remapping as touted out improvement, there is no blessed way to remap the rest of the keys.
That means third party deamons like Karabiner are the only straight option, and since it stopped being a kernel extension it's also out of the critical loops and will lag under load. In the worst moment I see keystrokes getting processed with enough lag to miss the combined triggers or go to different applications.
Windows has more options out of the box (e.g. 106 key layouts IME languages etc.), Powertoys is blessed and efficient, and AutoHotKey works well even under stress.
I'm still hoping for more improvement on macos land, but I wish there was less talk and more work on Apple's part.
