Dealership paint protection packages are typically just snake oil, overpriced, low quality, or all of the above. Working at a dealership, I saw plenty of people purchase something like that, and nothing ever even got applied to the vehicle. You're essentially just buying a warranty against paint defects.
If you're finicky about your paint, get it compounded and polished before having any sealant/wax/ceramic coating applied. A couple downsides of ceramic coatings are that it can give a somewhat unnatural look compared to a traditional wax. Additionally, you'll have to compound the ceramic coating off the car if you need to reapply or fix something.
