I’m not reading through that entire rant but 2 things I noticed with mouse input on Wayland:
On KDE, the mouse acceleration is horrible by default. However, setting “Pointer acceleration” to “None” in the mouse configuration solves pretty much all my mouse input issues on Wayland.
Also, I noticed that there is quite a difference between default polling rates on wireless mice vs wired mice. When connecting my Logitech Pro X wirelessly I get a 1000 Hz polling rate but if I connect it wired, the polling rate falls back to 250.
There’s nothing in wayland that would care about whether a mouse was connected wirelessly, but libinput may not be detecting it properly when wired. I’d try reporting it, the fix is likely to be trivial.

This sounds like some silly bug in libinput.
