Gnome and KDE are not doing the same thing.
KDE will continue to offer an X11 session for the time being:
Current status: Plasma’s X11 session continues to be maintained.

Gnome will disable the X11 session in the next release and then remove the code:
The most likely scenario is that all the X11 session code stays disabled by default for 49 with a planned removal for GNOME 50.

The Ryzen 5000 series should be a good choice for such an application, they’re still quite powerful CPUs. You should just make sure that you get the notebook/APU variant of the CPUs (e.g. 5600G or 5600U) and not the desktop variant (e.g. 5600 or 5600X). The desktop variant has significantly higher idle power consumption (see e.g. https://www.reddit.com/r/HomeServer/comments/1l707yc/nas_idle_power_usage/, they report 50+W in idle, while my 8500G system idles at 17W). The one you linked should be fine.
