Default Rod bearings and Piston questions

Disassembling my short block and checking my rod bearings . All looked smooth except for 2 . They have some ever so slight scoring in them. Nail didn’t grab and the crank journal looked polished as can be. What do I do in this situation?
Also I’m considering dropping in a forged set of rods and pistons. The engine must be honed and the pistons should be present when the shop homes the block right ?

I spun a rod some time ago and had then engine refreshed . To my knowledge it was turned .020 over,however I don’t recall if they turned the singular journal or all of them if that’s even a thing ?would this crank still be good for 7-800 whp? Or should I scrap it and buy an unturned crank?

Have it machined and balanced. Buy once, cry once.

You can turn the crank journals down way further than .020 before you have any issue. Hell, some years back it was popular to have turned crank journals down several tenths or more to a Honda four banger journal size.
