I have both on my car (PPF full front, hood, front fenders, rockers, rear quarters). If you go w/ PPF, go with a good quality one like XPEL. It is self healing w/ a little heat and resists yellowing. Note that you'll need different ceramic coating products on the bare paint vs PPF surfaces.
I wash my car at home w/ a pressure washer and foam cannon. I dry it with a leaf blower, so it all non-contact. The ceramic coating makes it easy to keep clean. Also, I use a mixed bed deionizer so if I have a few water drops left (mostly the wheels and under the mirrors) air drying won't leave spots.
