. In Wikidata, each entity has two URIs associated with it: the concept URI (.../data/Q12345) for the actual thing and the data URI (.../wiki/Special:EntityData/Q12345)

ITYM .../entity/Q12345.
Yes, the first one is the canonical entity URI and the second is data access URI and also entity dataset URI. We probably don't need both for Commons, since we do not plan to represent this kind of commons data in RDF, we only need to refer to it.

When referencing datasets on commons, we really mean the data, so we should use the URI of the data.

Again, since we don't have both wd:Q1234 and wdata:Q1234, it could be the same URI (or, alternatively, the only URI is the "URI of the data"). In Wikidata, it's different URIs because we have two different things. But for Commons, we don't need to represent these things, so we can just have one URI, since we don't really define what this URI is - it's never a subject for any RDF predicate as I understand, at least for .tab/.map data.

I understand you are arguing for having something like wdata: URI to be used. I am not against it, though as I said above practically there is not much difference. But I'd prefer nicer URI than wdata: - we didn't have a choice in Wikidata since we had to have two URIs and only one of them got to be "nice", but here we have only one, it may as well look like https://commons.wikimedia.org/data/Avignon_City_Wall.map. We could also use direct link but that IMHO is a) less nice and b) creates unnecessary binding to namespaces, which are also internationalized and it becomes kinda messy. I'd rather have clean static URL on the front and have it resolve to different things as needed on the back. And I'm very much for the URI in RDF not having any query params, etc. - it looks less nice and creates unnecessary dependency IMO.
