I'm replacing floorboards having rewired underneath
- nail or screw ?
what are the pluses and minuses of each?

Plan to paint it, so would that make the screws unscrewable?

PZ2 or another kind of head?

advice and experiences please

I would strongly suggest making the screws so they *are* unscrewable, and
not gluing the boards to the rafters. If you remove some of the screws, you
can paint that area and then replace them and repeat the process on other
areas.
