Going to a larger nozzle and kicking it up a bit on temp is going to solve a lot of the problems.

Slowing it down and reducing retraction will also provide some help but not as much.

Side note- use a hardened nozzle (micro Swiss is inexpensive for the occasional abrasive, but they’ll still wear, just slower. Diamond/ruby nozzles won’t wear nearly as much, or, at all but are expensive.) this won’t stop clogging, but it’ll wreck the normal brass nozzles and throw off your flow settings.
