Fedora is not enterprise grade. That would be RHEL. And entreprise grade mostly just mean stable (some would say stale) packages anyway if you don’t pay for support.
Installing nvidia drivers on fedora workstation is as easy as enabling rpm-fusion non-free and then installing a few packages. The issue here comes from OP running an OSI-based immutable system, which makes layering stuff on top a bit more difficult.
OP’s already running something fedora based, might as well stay where they feel comfortable and just add a few drivers and gaming tweaks on top.
Nothing against opensuse though. I’m currently running aeon because their approach of immutability is more modulable than fedora’s one.
