Most of the street-parking paint damage I have is on my bumpers - which is fine, they're called bumpers for a reason. The second most noticeable issue is the haze that develops on headlights over the years. At first, I bought the kind of headlight renewal kit that works with my cordless drill - polishing compound and sealant, etc. It was a lot of work, and only lasted about a year. If your headlights get hazy - just buy new ones on eBay.

On that note, the main thing I've done since moving to Philadelphia, with respect to my shiny vehicle, is get a sun shade for my windshield. There's only so much you can do about the exterior - might as well do what you can to protect the interior from the sun.

Had to get a couple of windows replaced recently because of vandals. I'd call them thieves, but there was nothing for them to take. The most recent one only shattered the window in place - Safelite used a rope saw to remove it, and scratched up my paint. They paid to get the paint fixed.

I think the reality is, living in an urban environment reminds you that a car is a utility, not a trophy or a work of art. Certainly not an investment, either. You know what (typically) helps with accepting that your new car will get dings, will have strangers leaning on it, will get broken into? Buy a slightly used car, and put the thousands of dollars you saved into an auto maintenance account.
