The attaching to the nozzle for PETG usually meant the flow is too high, also visible from your top surface - not suppose to have ridges and the small holes re probably from uneven distribution of PETG from the already attached on the nozzle residue

i do not think you have VF is problem , on my Profile is 20 , but i reduce it if i want to change the speed
and i limited the speed to 140mm/S any way . Usually around 6-8 is a good number for slow print -
PA(K) factor is way off this is the small ridges around the hexagons
-
avoid grid infill for PETG , either gyroid or rectlinier

Part fan cooling needs increasing
I think i sent a few times the calibration link, but hey
welcome to bambu , but still the best printer of all i have had . And i gave up on Bambu profiles about a week after i got the printer.
Your Flow and PA will be different the rest should be the same
Note that from 3 PETG brands noticed that PA of 0.05 usually works ok for PETG with out tunning, but still check it any way
EDIT:
@ExtremeElementz I noticed that on my profile for PETG the AUX fan was changed to 0% that was for testing issue with huge plate. It is suppose to be between 10% and 30% depending on the M106 P3 S150 see the note , but this is your last cherry, 30% should be with S150 but you can play with it. 0% may affect your print but anything between 10 and 30% should be ok
