Consider post processing steps if you really need smooth parts. Sandable fillers, special paints, epoxy coatings, or just a bunch of sanding. I’ve had good luck with XTC-3D. It’s an epoxy you paint on that’s specifically designed for smoothing prints.
You could also consider a resin printer if you need smooth. They are their own can of worms, but the resolution and smoothness is good.
I usually just accept the roughness.
