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 easiest distros to run Resolve would probably be Rocky Linux 8, Alma Linux 8 (both are based on RHEL 8). Instead of the EOL Rocky/Alma 8.6, you should use release 8.10 (8.6 would update to 8.10 anyway). However, while still currently “supported”, these are still shipping (mostly) 6-year-old (!) packages. Also, only a small number of packages is actively supported by Red Hat. IMO, this implies that these distros offer a lower level of security. The most critical parts (browser, kernel) are still well-supported, so the difference is probably not too large for most regular users. However, you may also struggle to run some other software (although Flatpaks are available). It’s unfortunate that Resolve only supports an ancient version of Rocky (Rocky 10 is now out)…
