I’ve seen a number of dealerships try different products from the numerous Guard or claimed Ceramic coatings. My response is always no!
If you really want to protect the paintwork then find a detailer who will clean the car and apply a decent protective layer but nothing is permanent. They’ll all need a top up after time, whether it’s 2 years or 6 months.
Given it’s a lease car, I’d just wash it regularly and be done with it. You’ll spend a small fortune for no real benefit if you protect the paintwork.

I'll try to give my honest opinion but am always open to learning.
