Leaves really only need to be removed from sidewalks, etc., where they might cause a slipping hazard, and away from storm drains. Five minutes with a stiff broom should do the trick. Unfortunately, a lot of “mow & blow” outfits blow leaves into the street and don’t pick them up. I also remove leaves that collect on evergreen shrubs (especially conifers) to prevent damage to the foliage. Otherwise, leaves provide beneficial mulch over the winter. I usually do my leaf cleanup in the spring, and then only in more formal planting beds. In healthy, naturalistic plantings and landscapes, they can be left to compost down.
