Wayland has a massive loss in functionality (in the name of "security" and off-loading implementation details to compositors/window managers) compared to X11 though.
Stuff like xdotool, screen sharing, clipboard sharing, etc. is much harder.

When was the last time you really tried wayland? My first (and last) time was 2017. Much has changed!
In a few years, when wine support is perfected, I think people dissing wayland will be seen as quaint as those insisting on a distribution "unsoiled" by systemd are seen today :)
We only have to wait a few more decades at the outmost.
The underlying problem is that the protocol (ABI, really) has to be specified and implemented for these things to work. Screensharing was a prominent early example of something which hadn't been through that process. It was a very visible issue, an easy wound for hardcore X11 fanatics to pull at, and - apparently - continue to bash on long after it has been solved.
Clipboard woes have likewise been solved.
Mouse and keyboard injection has not yet been solved, but I recall there being some draft spec to that effect.
Ultimately, if Wayland does 100% of what you need, you should be using it because it generally does those things better. If it doesn't do what you need, then stick with X11 until it does (and support for that protocol is widespread).
