Not much to figure out, just make sure to not get the flatpak/snap. Any non-arcane distro should have a working package, the trick to packing steam being not trying to be smart about things you basically have to give it a libc, gpu, and FHS (chroot or not), it takes care of everything else.
This should not be seen as advice for anyone but a very small number of people:
There is a good purpose for the flatpak. My use for it is Squad’s anti-cheat uses I think a depricated function in C, and the most updated version of glibc doesn’t support it anymore. The flatpak does contain a version of glibc that works, so I have two versions of Steam installed on my system. I only use the flatpak for Squad, because that’s the only game with that issue.
In principle steam should be able to manage such things by using a different runtime for the game.
