Personally I cannot imagine going into someone else's game with a concrete character concept that I absolutely must play. I want to discuss the campaign world, what fits with the world and the rest of the group is interested in, what the pitch is for the campaign or what we as a group decide we want. I may have had some vague ideas that may have been fun but they just didn't fit with the group or what the group wanted to do. I'll just file away that idea in the "nice to play someday" file and pick something that will fit. If that means I wanted to play an elf and there are none in the world I'll figure out something else.
If someone does join a game with character sheet in hand for a session 0, not just a concept or something they'd like to run but something they absolutely must run, to me it's a potential red flag. We're going to have to have a discussion about what that player wants out of the game because it sounds like someone that's making demands not just of the DM but the rest of the players at the table.
