If I go the BMW branded oil route, do I buy the LL-01 spec or the LL-01 FE spec 0W-30 oil? I have a 2018 M5.

You'll be perfectly fine. Engine will be perfectly fine. BMW will probably change their specs in a year making today's oil out of spec that you've been putting in the car since day one. Not much changes and it certainly won't damage the engine.
