If you don't care about the car looking good then definitely don't get PPF/ceramic coating. They do nothing for resale value. If you do care about having a car that looks good, is easier to wash, gives off that oily shine, and you would like to reduce blemishes from debris, then PPF & ceramic coating are well worth it.
My experiences so far having my Model 3 for 2 months now, is I've gotten my front bumper scraped by a car in a grocery store parking lot, and a rock the size of my thumb launched and stuck on the front of my bumper. Luckily, I did have my front bumper wrapped, so the scrape was wiped off with no damage under the wrap, and the rock I peeled off and the wrap self-healed with again no damage to the bumper. Both of these cases, had I not done the wrap, they would've caused paint damages. I got my money's worth in just 2 months, and I cringe when I think what might come next.
If you do care slightly about the looks of your car, then please get the front bumper wrapped. At the very least, do the front bumper. Out of all the places on my car, the front bumper is taking the most beating. The hood hasn't had anything happen yet (knock knock), but the front bumper is attracting debris, bug guts, and inconsiderate bad drivers.
As for ceramic coating, I did it to make washing my car easier, and to hold that oily shine longer. There's no debate about it, ceramic coating last a lot longer than wax. If you feel like waxing your car often, then sure, don't get the coating just wax the car yourself. But it's hard to compare to ceramic coating that is thicker, semi-permanent, and has great hydrophobic properties. All of which allows you to keep the car looking good and shiny easier.
