Paris in particular comes to mind as a place that has really nice (calling them really nice might be a stretch, but they are mostly functional and taken care of) public toilets in regular locales through the city. Otherwise the typical M.O. (though this is unfortunate for lower income populace) in the US city is to walk into a food service or bar establishment, purchase the cheapest item on the menu, then use the facilities. Even this is somewhat difficult however in the COVID era when many lobbies are closed and there is takeout service only.
