Does it need to be fully automatic, or does semi-automatic work for you?

I am using input remapper to automate a few functions of my input devices. It only used it on my Plasma desktop, but it should work in all desktop environments.

xdotool should work the same in the Wayland session, assuming you give X11 apps the permission to emulate input. What about it isn't working?

The proper way to programmatically move a cursor on Linux is using uinput.

Anything you were doing that worked in xorg and not in wayland was more akin to a weird remnant from the 80s than to an actual solution.

However, there will likely be full featured applications that already do whatever you were trying to do.
