[Q] Selling N4 with PA, what to wipe topic

I have a custom ROM (PA 3.99) on my phone. I am meeting a guy tonight to sell it, and my new phone comes tomorrow. So I need the phone up until I meet the guy, so I will wipe after he agrees to buy. What all do I wipe to keep it working, but safely remove all my settings/pics/etc...? I'm on TWRP recovery.
