The pistons moved smoothly when I pressed them back into the caliper with my fingers.

At this point I'm trying to decide if there's any risk from just living with the creak, or if it's a leading indicator of a bigger issue. Any suggestions?

A few more details:
1) I've got 25,000 miles and 30 track days on the car
2) The piston dust boots are cracked
3) The only potential next step I've come across is doing a caliper rebuild; I'm not sure if this is necessary.
if no fluid leaks, piston not seized and no abnormal brake pad wear you are good to go.

Lube the guide pins and end of the pad backing plates and see if that does anything.
