After testing the lessxwl and differentxwl repos, I think the best approach is lessxwl,
especially because Firefox prefers Wayland on that configuration.
Both repos were tested for about a week, and I think I'll go back X.Org for now.
Telegram (Flatpak) and Firefox crash at least once every two hours, and the fact that
spanish accent marks are not working on Qt apps (that includes LibreOffice for some
reason, probably because the Qt version is the one shipped with Plasma).
Minecraft worked fine with the Intel GPU, and NVIDIA, of course was NVIDIA, as usual, no
need for details.
* Minecraft works over XWayland
Either repo was clearly a better alternative than the current implementation.
Also, the rectangular selection issue with Spectacle has been fixed with the version
Vivaldi also worked fine on the lessxwl repo, and definitely crashed less than Firefox.
(and no, I won't try Edge :p)
The change to either repo was seamless for me; in my opinion we can for the scream test.
