WinApps is the project to watch (https://github.com/Fmstrat/winapps), although they're still working on Wayland support (https://github.com/winapps-org/winapps/issues/779#issuecomme...). It can get by through xwayland for the time being, it seems.
Also, sdl3-freerdp is the new Wayland client for FreeRDP is already available, and it works fine. You can just edit the shortcuts/bash scripts and replace xfreerdp with sdl3-freerdp and bam, you've got Wayland support.
