The best way to link objects from Wikidata and Openstreetmap is by adding wikidata tags to the OSM objects. That way those Q-numbers can follow along when an OSM object gets converted from a node to a way (POI to building for example) or from a way to a relation. (area to a multipolygon for example).

The best way to figure out which objects are connected is the Overpass API. It would be a good idea to have a poperty on the wikidata side where Overpass Queries can be stored.

How so?  Oh, because Wikidata is CC0 and the Open Street Map database is
ODbL, which is somewhat like CC BY-SA.  I don't think that that follows,
though, as what is being put into Wikidata is contents, which appear to me
to be covered under the DbCL, which is like CC0.
