I’ve never used Mint and I don’t get the hype. I didn’t have to modify anything on endeavourOS for stuff to run. All I do on endeavourOS is yay to get updates and install via yay -S [pkgname].
On endeavourOS I run Steam via flatpak since it uses 32bit libraries, so I personally prefer it separate, but I used to have it non-flatpak and it worked normally.
