Some thoughts:
CHILDREN OF DIFFERENT HUMANOID KINDS
In principle, I don't have an issue getting rid of Half-Elf and Half-Orc, but this seem like a clunky solution. The way Level Up handles this is a lot more elegant.
HUMAN
Why are you here human, don't you know your ABCs?
ARDLING
That name. If they're the Teifling's opposite number, maybe they should call them Hochlings.
Mostly flavor issues with this one. Give the option of dialing the zoomorphic appearance traits up and down to taste. Also, why wings? Maybe I want my monkey Ardling to fly on a tiny little cloud!
DRAGONBORN
Seems a bit of a nerf from what was in Fizban's.
DWARF
Seems pretty good, except Forge Wise. If you need a "a god did it" to explain why this is there, time to go back to the drawing board.
ELF
Elves gonna elf.
GNOME
Forest Gnome's speak with animals ability is no longer at will, but the silly small or smaller beast restriction is gone. Proficency bonus uses per long rest, plus added to your spell list. I like it. If they added Fade Away I think this would be solid.
Rock gnome's get the Mending cantrip and can put any Prestidigitation effect into their contraptions. These are long standing house rules we've had, so kudos.
HALFLING
These are here.
ORC
I think these are unchanged from Mordenkainen's.
TIEFLING
Glad to see some of the pre-4E diversity returning to these guys.
