For dense-deliveries (e.g. mail) park legally and walk some sort of cart along the sidewalk for blocks. For sparse-deliveries (e.g. food) ebikes work great. For medium density (e.g. puroloator) cargo-ebikes at least greatly increase the number of out of the way spots you can park.
Larger scale deliveries (e.g. to malls, grocery store, factories) should have a privately owned off-road, built into the structure place for trucks to park and drop things off. Though things like factories often simply don't belong in the dense part of the city.
This is pretty idealistic. What winds up happening around me is the amazon guy parks their car in the middle of the road AND also has a cart to hit multiple houses at the same time in that region. Furniture deliveries or even moving trucks can block our street for 30 minutes at a time. It is almost as bad as garbage day (ya, you aren't getting through our street on Tuesday morning if you time it wrong).
This would all be solved if we just had delivery parking spaces and got rid of on street parking for everyone else. Really, just that part is just where everything falls apart quickly. This is why traffic seems so much better in Europe (at least where I've lived, like in Switzerland), deliveries work, cars are not parked on the street except at a few very expensive parking spaces.
