Any rubbing technique will have to be done everywhere because it will change the sheen.
One way is to use finest steel wool, and go in one direction, usually with the grain, then vac. off the dust and buff.
Another way is to use a fine abrasive paste or powder, like a buffing compound or rottenstone + oil.
The best way to get the nubs down is with a fine sandpaper (1500 grit) and water plus a drop of detergent. Using a rubber sanding block, gently sand with the grain; wipe off the slurry, then use the rottenstone.

Nothing is perfect.

I'd leave it be since you're happy with the finish.

Time will take care of the "dust nibs" with use.

Thanks very much! I'm going to let it cure for 30 days minimum and think about this in the meantime.

Zagut- I was wondering if it might just work itself out with use!

Another woodworker who does a lot of You Tube videos recommended using Turtle Wax rubbing compound on a cotton cloth.

Any sort of abrasive, even a paper bag.

Which abrasive you choose will determine the final sheen.

I used a "magic eraser" to get a few bits of lint off my counter. Done gently, it knocks the lint off without affecting the satin gloss much.

I'd never heard of the brown paper bag method - worth keeping in mind.
