Ideally I want a database that contains all points on the earth down to about 3m by 3m square and a corresponding street address if one exists (might be a many to one relationship).
Does such a DB exist, and, if so, which is the most comprehensive?

Nominatim has an API that gives data on at the very least the street level. You can provide a latitude and longitude and have an address returned.

A gazeteer or big list of places, each with a stable identifier and some number of descriptive properties about that location. (https://whosonfirst.org/what/)
