I suspect that https://query.wikidata.org can count how many times each property is used.
Amazingly, you can (I was surprised):
https://query.wikidata.org/#SELECT%20%3FanyProp%20%28count%28*%29%20as%20%3F...
This shows the counts of *all* 8000+ properties used in the RDF store. Looking for the appropriate URIs, you can read off each Wikidata property's uses in statements, quantifiers, and references individually. I am impressed by how well BlazeGraph is handling this.

Now I suddenly understand why we should have "properties for properties" so we can categorize these things. It would be nice to have a list of "authority control" properties and also the number of times a property is used. Maybe there is a way to organize the metadata so a "property property" is unnecessary and another "category-like" tool can be used to split these up - maybe a hierarchy map?

Showing the shortened property classifications under "use" is a very good idea!
