Sturdy trees are good in the city, since they are low upkeep and very good for air quality and shade.

Sturdy trees WOULD be good for the city, yeah. Unfortunately we've decided to, in basically every major city (at least here in NA and I suspect other places), plant non-native trees that have low survival rates and are basically all male. Being male, they tend to also shit pollen basically everywhere. I'd imagine you could deal with the fruit falling to the ground in a number of ways, as well. Could put some canopy underneath the fruiting trees, as to collect the fruit more easily, you could just pay people to come and collect enough of the fruit for use in things like applesauce that the rest of the fruit really presents no issue as far as just sort of rotting and draining into the ground. You could set up a bunch of easy disposal compost boxes every couple feet, so you can just sweep all the fruit up and throw it into that.

I suspect a larger problem would probably be that inside of the city the fruit would be exposed to more than an acceptable amount of brake dust, including that which drains into the planter box, and would maybe not get enough light, but I think those are generally problems we should be solving anyways since they don't disappear just because we decide not to plant fruit trees. Brake dust on the fruit or carcinogens inside the fruit means that those things are also going to be going into your lungs.
