No, it's not worth getting PPF and ceramic coating. It is like wrapping your furniture in plastic, then putting an expensive coating on that plastic hoping that it will hold its value.
When was the last time you saw a classic car with PPF installed? Ceramic coatings can make sense after paint correction mostly for ease of cleaning and if you just like your car looking as good as possible.
You will never get a return on investment from PPF or ceramic coatings; they do not add value to your car. Go to sell your Model Y to Carvana with rock chips and scratches or with fresh PPF, which you will need to replace every time the rock damage builds-up because the rock and debris strikes actually tear the PPF back (will not self heal from avulsions especially once they get dirty) Carvana will not care about your PPF. If your PPF is not fully wrapped around components like the facia, there will be a line of dirt around the edges constantly which etches the clearcoat of the paint.
Lets say you just do clear bra (PPF) at the facia and hood, your paint will wear unevenly due to different UV exposures and you will have those constantly dirty PPF edges. Add it to the A-Pillars and side mirrors; where do you stop?
My $0.02 is that your Model Y is a vehicle, not a museum piece or a priceless baseball card. You could pay a Tesla approved body shop to re-paint the entire front end for less than the cost of properly installed PPF + Ceramic Coating. Why spend probably 5 figures installing/replacing PPF and ceramic coating over the life of ownership when the paint you are trying to protect (solid black) is very soft and generally poorly finished from Tesla paint shop and pre-delivery? I would just enjoy the car. If you still have it in 5 years consider paint touch-up and wet sanding/detailing or re-paint damage.
