I'm very new to ARs, but not to lubrication of mechanical components.
A general rule of thumb is if it doesn't have a dedicated system to provide oil to the components, grease is the answer for high wear areas.
Obviously slathering your BCG with thick grease might not be a good idea however.
I put NLGI #1 or #0 grease on the bolt lugs and cam pin. A thin, thin layer of it is all you need.
The other parts get CLP.
No malfunctions or significant wear marks on a brand new (cheap) BCA complete upper.
