Generally, I use grease on 11, 1, 5 and 7 o'clock positions on the bolt carrier.
Grease on charging handle 12, 9 and 3 o'clock positions.
FCG will get light oiling, only when necessary.
One place people neglect in the buffer tube. Most of the problems people have with aftermarket bolt carriers getting stuck half charged is because the rear of the bolt carrier on the 12 o'clock position is dry. A little grease here helps significantly.
Other than that, inner barrel and hop up bucking dry and clean.
