FWIW, I don't have much of a problem with current slot_ names.

Hm, I guess that depends on what you classify as type independent. Is
something like slot_getattr type independent, even though it internally
calls slot_getsomeattrs, which'll call a callback if additional
deforming is necessary?
I'd say, if you exclude functions like that, ExecStoreVirtualTuple(),
ExecStoreAllNullTuple(), slot_getmissingattrs(), ExecSetSlotDescriptor()
are probably the only ones that have no awareness of the type of a
slot.
I'm not sure it matters that much however? Unless you store something in
a slot, code normally shouldn't have to care what type a slot is.
