Use Wikidata for place names and Wikipedia descriptions

FWIW, one impediment is that I personally find the Wikidata SPARQL API pretty mystifying. If someone could provide a working example of how one uses it to, say, retrieve a Wikipedia page URL for a taxon given an iNat taxon ID (or s/taxon/place/ to keep it on-topic), that would help me out a lot. @tobyyy, maybe you could provide an example?
