Skinned mesh renderer quality not working right?

Hello! So I (still) have issues with my model, primarily that the wrist doesn't bend properly

Blender: Rig: (The forearm copies 50% of the handbone's rotation locally) Unity:

And my frustrations keep going as it seems the closest thing I get to a proper bend is at 4 bones in the skinned mesh quality setting,

But this subsequently makes my character's face look like it has been run over, or as if their DNA was spliced with a bulldog. Certain faces bend in unintended ways

The main candidate here are the eyelids, whose bones aren't meant to deform (and subsequently do not have any weights besides having the eyelid sphere parented to them). When I turn the quality from 1 bone to 4 bones, the face seemingly crunches up as a result of eyelids closing.

Any suggestions?
