Bellingcat's Bellingcat OpenStreetMap search is a tool that wraps Overpass Turbo in an easier-to-use interface for the specific task of geolocation based on image and videos: https://osm-search.bellingcat.com
This is awesome, but a lot of the queries I've tried to make seem to fail on OSM's data itself, which is sad. For instance, "coffee shops within a certain distance of fast EV chargers" would be really valuable, but the underlying data just doesn't have that EV data. So it's cool for a lot of stuff, but mostly explicitly streets; the other kinds of nodes all exist but aren't as well fleshed out as they could be (totally understandable).
