I understand what content-location is and does. I don't understand WTF
you're talking about with regards to it and this canonical thing. They
seem entirely unrelated to me, so referencing one from the other
doesn't make any sense.

This doesn't make any sense. If you use a particular permalink
structure, then the canonical URL for your posts would reflect that.

Also, the fact that you have no index and use only categories doesn't
affect this either. Canonical URLs would only make sense on single
posts/pages/attachments, they wouldn't be on an index or an archive.
