would it be smart to polish these?
Yes, of course. Did you expect a different answer?

If so what tips do you have to polish these besides Kiwi Parade Gloss and time?
Not sure what you're looking for here. There's really not much else to it. Just gotta get a decent quality polish (Kiwi parade gloss is what I use too) and spend the time doing it.

A good applicator brush, as well as a buffing brush will help. But really, the fine-tuning of a good polish job is in the elbow grease, done with your finger, polish, and moisture.
