Apple: (I guess Apple maps can't be linked to on the web?)
It also helps a lot if your government can be persuaded to open up their geographical data. All the building outlines are right there on the map in the Netherlands, up to date to within weeks, because the Dutch OpenStreetMap volunteers work with government data that is permissively licensed and cleared for use with OpenStreetMap. In fact, mistakes in that data set are also picked up by the local OpenStreetMap mappers, and reported back to the government cadastral map. Everyone benefits.
FYI, you can link to Apple Maps [0]. The equivalent URL isn't really much different [1]. A bit unfortunate that there's no consensus on the URL params between providers, though.
Trying to open that link on macOS from either Firefox or Safari shows a modal asking if I want to open it with the Maps app. I'm not sure what happens on iOS, but I'd expect something similar.
IMO, the lack of web client for Apple Maps makes it the worst of the bunch. Vendor lock-in is a tragedy.
I've been trying to use OSM more over the last few months, but it's hard to compete with Google on their home turf. Although OSM started to become more appealing as Google began requiring you to enable all sorts of data tracking for many or its features to work. If you disable location tracking you run into all sorts of bugs.
Compare this section of a Dutch city:
