Well I've just finished a game jam using exports from CC. Sadly I had to ditch all the shaders for it - the URP skin shaders weren't compatable in webgl, but easily replaced with standard shaders and real toon ones. Which kinda upsets me a lot because CC is hands down the best shaders for unity out there and has been for a long time. The ability to downgrade to regular shaders was also very useful.
CC has great skeletons, and is compatible with salsa one click for lip sync, so setting that up was a breeze.
I imported some objects and a character from Daz. The toon rendering allowed me to strip textures to 64x64, with some faces at 256x256.
Some major issues are:
Is not being able to select morphs exported or export body morphs. If we could do that then CC would be the premiere character system for unity, rather they've trying to protect themselves I think - A full blown character creator inside unity that you could use like meta humans would be super helpful.
^ this leads to really large fbx - 25 meg just for a fbx character, without including textures! My game was 118meg and 2 chars took up 50meg plus of that, which is a bad, bad thing for web games. I think you can strip morphs in blender somehow. Not a big issues when porting to PC though
