Most likely culprit - BB or Cranks. Remove crank and BB, clean everything properly. Put grease on all threads (including bolts) and axle. Refit. Check all chainring bolts are thight.

Second most likely - QR. Do the same, remove - clean - grease - refit.

 

Third most likely - stem contact points: handlebar or steerer tube. Do the same, remove - clean - grease - refit, Except the steerer tube - do not grease. Also note - fancy carbon might have issues with grease.

 

Note: Putting a thin layer of grease on axles serves no other purpose but to check next time (when you remove) if grease is still original color or contaminated. If the grease in the axles are contaminated in could indicate the need to service your hubs/etc.

 

Creaking noises when seated usually comes from seatpost (grud in the slit/sleeve) or grud in the rails of the saddle. Again: remove - clean - grease - refit.
