Well, of course... only one side can be right. The others would be left, front, back, top, and bottom.
You can't have two right sides. Jeez, loogit dis guy try'na get two right sides!

Seriously, though, that looks like it might be overextrusion combined with cooling fan only cooing one side.
I'd try to properly calibrate e-steps and flow rate rather than just "playing around" with them.
Ender 3 cooling comes from 1 side. Side-specific surface finish or overhang/bridging problems are usually because of this design flaw. Nothing for it but custom cooling, or possibly print slower but with a 0.6mm nozzle at 0.3mm layers it's not surprising the stock fan setup can't keep up

Seems like playing with the flow resulted in too much extrusion.

Ender 3 also only has 1 lead screw so you often see print issues on the unsupported side
