Since it took bit of time and multiple broken links to find: https://categoricaldata.net/examples has links to a lot of info about CQL for learning/comparing/etc.

(edit: in retrospect, this is just the "getting started" header link, despite the URL)

Unfortunately none that I've followed seems to do much to describe much of anything except the math foundations. They might cover pieces of syntax, but not how to use or think about them, and they seem to be rather excited about the data-generating features that I can't imagine anyone using outside tech demos (unless that's the only insert method? what about update?) :/
