He / Him
That's what we agreed to when I ran Curse of Strahd. To fit a more gothic theme, we opted for Human and no more than one of elf, dwarf, or half-elf. It felt more immersive for us, especially given Barovia was almost exclusively human (with a smattering of dying elves), than throwing in a dragonborn or tiefling or even jolly gnomes. Those would fit better in another story.
I think this approach is totally legitimate. I went with the opposite approach in my CoS-inspired game. I changed the races of Barovia to match those of the characters! We wound up with villages of oppressed tortles and lots of Tieflings. It's been a blast!
