So I've dealt with the dreaded pockmarks for years and tried literally everything.
Filament dryer, extruder calibration, all the external stuff.
I spent the last few days straight printing 10s of test parts adjusting the following settings.
Extrusion multiplier, pressure advance, wall thickness, retraction distance, extra retraction + and -, nozzle wiping distance, printing inside out vs outside in, temperature, cooling, part orientation... you get the idea.
When I finally just looked closely into the G-Code and the preview of printing I noticed it's exactly at the spots where the nozzle moves from and inner to outer perimeter or vice versa aka it's 100% a Z-Seam issue.
You'd think wipe would fix this but it didn't.
What FINALLY fixed it is setting Simplify3D to "Restrict start points to preferred regions" and that put where the nozzle movement between perimeters into the inside edge of 90 degree turns or the best spot it can find close to that. This one change eliminated pockmarks altogether for me.
I'm sure other slicers have a similar setting but I can't speak to that cause I just use Simplify3D.
But even if there isn't an automatic button for it, I'd recommend choosing a start point in a corner to hide any seams.

My prints are now nearly literally perfect.
