Nothing, unless you really want to use a DE that’s still lacking behind in its adoption. There are a few tools that still only offer early support for it (like RustDesk), but otherwise Wayland is a way better choice these days.
However if you got an Nvidia GPU and need to use the proprietary driver you might be forced to still use X11. Their pile of garbage still routinely bugs on Wayland, and given their work on NVK I doubt that thing will ever get fully fixed.
