DarkCrisis
Let her cook.
given there are 10 (11 if dark origin had been it's own) companions and 11 species i'm surprised they didn't choose to have each companion be one of each species, there are three humans, five variants of elf(1 high(also vampire), 1 wood, 1 drow and 2 high half-elves), one tiefling, and a githyanki.
i haven't actually played BG3 so i don't know the characters extensively but going off the wiki what if:
Dark Urge - Dragonborn
Astarion - Elf (wood)(vampire)
Gale - Gnome
Karlach - Tiefling
Lae'zel - Githyanki
Shadowheart - Halfling
Wyll - Dwarf
Halsin - Half-orc
Jaheira - Half-elf (high)
Minsc - Human
Minthara - Drow
i don't really know why they felt they had to separate drow from the other elf subspecies but it is what it is.
Durge can be whatever but default is Dragonborn
Shadowheart is a Half-Elf
Gale is a Human
Wyll is Human
Halsin is a Half-Elf, I think? or Human? He's big and bulky.
None of the companions are a short race by default
