I like the idea of making half-races as variants on the base race.
I also have a bit of an issue with a world being populated by dozens of intelligent races. It's one thing to have a Star Wars cantina scene in space fantasy, where you have any number of habitable worlds.
I'm still not entirely convinced that we have evidence that a world can be populated by one intelligent race.
Let anybody play any race, but eliminate all rule mechanics related to races.
I'm not a fan of the monstrous races (orcs, goblins, kobolds, etc nearly all the stuff in volos, all the crap you always see someone trying to make a PC out of - vampires, lycanthropes, etc etc etc), drow, & durerar as PC options. My view is that monsters are what your fighting against, looting, & getting your xp from.
If you have an idea for one of these? Sure, ask me. But be aware that I'm almost certain to say no. Because I don't run games where those would generally fit as options.
I could also easily live without dragonborn, tieflings, warforged, genesai, shifters, traditionally non-evil "monstrous" races (tritons etc). Again, ask. You're odds are better than the previous category though....
Humans, elves, dwarves, 1/2lings, gnomes, 1/2elves, & 1/2orcs - no problem, though depending upon where on the map the campaigns occurring some of those are more/less common. So take that into account. For ex; In the upcoming campaign true elves have largely abandoned the region several hundred years ago.
