I would get a set of mixed bits but then a multipack of PZ2 bits, as that is what I seem to see most commonly. So nice to just switch to a fresh bit when you notice a bit of slip/cam out. Also, go for the longer bits like the below unless you are using a bit holder/extender. As has been said, the 25mm long bits will be too stubby.

I’m thinking, as I don’t see it having much regular use, maybe use what I have and if they break, just replace them. Might be more expensive but not that expensive really. I have no real need of boxes of bits as spares albeit I have a few for screws etc.
