Depends on the context of the setting and the story. I mostly tend to allow all official PC races without any objection. I see an adventurer as an outlier of society and not the norm.
In the games I tend to run I either swing between everything is allowed or just one is allowed.
If I want to do an mini adventure about a goblin clan fighting a kobold incursion, then everyone is playing goblins.
Jorge, Kyle and the others over at ublue is doing a great job with their Fedora spins.
I run Bazzite on all my computers and if you got a full AMD system you can even get full gamemode running by installing the deck image. This in turn give you the best controller experience for games, as Desktop Steam got several issues with Steam Input valve have not fixed yet.
But not all credit should go to them for this but also ChimeraOS team, Nobara and others that are constantly working on an improved gaming experience on Linux.
When developing RetroDECK Steam Input profiles I mainly use the Steam Deck with SteamOS and Bazzite on my desktop to test them.
