In my experience of games, players end up with a real United Nations of races when they pick their characters. The current party of the D&D game I'm currently in (on hold overt Covid lockdown but still alive) consists of a tabaxi, a halfling, a triton, a tiefling, a half-orc, and two humans (including my own - I started with a aasimar and have also played a vampire PC in that campaign). In that respect, the companions we have on offer in BG3 are actually not far off the demographic in terms of non-human to human races.
