gnome is cool for wall vision + shrink without needing to illusion yourself. tinkering is neat too.

dark elf is cool for ultravision + hide.

high elf is the best from a straight stat perspective but doesnt get the perks of the above 2.

human is neat because it gets some extra carry weight. the extra stam doesnt hurt either but int caster hp return from stam is kinda bad.

none of the races are a bad choice and if you have any aesthetic preference (you can always illusion, but its removed on zone and can be annoying to upkeep etc) or care about hide / tinkering / vision i'd personally let that be the deciding factor.
