About a few years ago, I tuned my old SnapMaker A350 to just about perfection. Unfortunately I had no clue what a profile was, and lost the settings. I have literally no clue what 13 y/o me was doing, because whatever it was, it was good enough to vanquish the dreaded hull line. All I can remember is that I did it with 0.08 mm layer height and tweaking some of the more basic parameters (I didn't even have all settings enabled at the time). I put a picture of that really nice benchy I made next to my most recent one. I made sure the bed and other hardware components are tight and secure, so the only physical thing that may have changed is the filament may have taken on water (which I am bed drying the roll as this is being written.) Any advice on how to get my old quality back?

Drying should do 50% of the work, but also check the mechanicals. (Belts \ vwheels\ oldham couplers \ lubrication etc)

Calibration
Calibration and tuning can help with all aspects of print quality.
Extruder calibration should be done only once, and then again if you change any hardware on your extruder setup (new tube, gear drive, different motor, etc).
Flow calculation should be done for every filament, even different colours from the same brand.

A number of calibration and tuning guides exist online:
