This is a conflicting argument I have playing out in my head at the moment as I await a new car..................
Modern ceramic with higher resistance to just about everything, along with increased longevity, easier cleaning and next level hydrophobics to make drying quicker................or......................traditional polymer sealant or carnauba wax that gives such a lovely look and feel to the paint, decent longevity for garage queen statis and more flexibility to try different products.
Personally, if you like what DGPS does for you, its such a lovely product in how it glows and that slickness. If you wanted to go for something more durable, try another ye-olde product in Collinite 845, which also has that glow and slick feel. For both, just use a spray wax/sealant as a drying aid and you will easily keep the car protected.

If you want to try something new but don't want to make the full leap into coatings, then Gyeon Can Coat EVO would be an excellent choice. Think of Can Coat as a gateway drug to a ceramic coating. It won't outlive a full-fat ceramic coating, but it will give you the crazy hydrophobics and chemical resistance. Longevity is stated "up to 12-months", I have easily got that and then some on a daily driver parked outdoors 24/7. Using an appropriate drying aid, then a decon wash with a higher pH soap every couple of months, I got 15-months out of Can Coat EVO.
