I also agree with @Aravisian:

What is better to use, Wayland or x11?

Everything will Work. X11 Is the standard stable Display Protocol. Wayland is an experimental unstable Display Protocol. There is much that does not work on Wayland, including Rermmina and Nvidia.

and the inability to share desktop and video conferencing, my secure preference once enabled, being Jitsi.
