Tesla hardly gives you your "monetary return" on the vehicle it's self. They are NOT in the business of taking trades and selling them like most dealers. These cars are usually shuffled off to auction or a 3rd party to list and then sell through Tesla. You'll likely get a horrible offer from them, but there is the ease of use of driving your existing car to them, signing papers, and driving away with the new car, plus if your state allows, a tax break through the trade.
I believe Tesla usually just goes by KBB or someone's standard on "good", "fair", etc condition. A few rock chips probably won't hurt trade in value, especially if you get a paint touch up kit and go over them. I haven't personally done it, but I think Tesla "glances" at the vehicles and just makes sure they're in the working condition you describe and don't have big dents or large (multi inch) scratches.
CarMax is almost worse then Tesla. I had full paint protection film on the front of my vehicle and only 7,000 miles after 1 year and CarMax mentioned the whole front end would need to be repainted because they saw dead bugs (I live 150 miles away from CarMax) on the front and thought they were rock chips. After I pointed out those were bugs, they just said "well, even if we had to repaint, it doesn't change the quote at all, we paint in house." So..... they either don't care about things like rock chips, or they just already factor in refurbishment costs into their quotes.
Private sale is going to be the best, other then that it'll be luck of the draw with CarMax, Vroom, or Carvana. Right now values are high, but I think that's likely because Tesla is still "hot." A few years from now if anyone can walk into a Tesla store and get a brand new model in a day, and loads of used Model 3 and Y's are on the market, I expect the value will fall in line with anything else in that price range; it'll tank the first year or two and then level off for a few years.
Edit: If you want any protection, JUST get the front bumper done, not the hood or sides or anything else. I can't imagine that would be more than maybe $500 to $600 and it'll keep the car looking nice for you. 100% you'll then get a rock chip on the hood just past the PPF because that's how the universe works, but at least the largest area that's likely to get rock chips will be covered for the minimum cost.
