Hi Andrea, I recommend the Manage data tutorial. It's not specifically about how to use the catalog view, but you do use it a lot in the tutorial. It will give you a pretty good sense of how to do things in Pro from a catalog view perspective. It includes working with metadata (viewing, importing, creating thumbnails), some other things unique to catalog views (viewing items as tiles), and common tasks you can also do from the Catalog pane or in other ways (search for data, add data to a map, create folder connections, change default items, etc.)
It's kind of long, and also has a lot of geoprocessing stuff that may not be as relevant to you. Comes with a 10-minute video, although I think you'll get more out of doing the steps.
I don't know of any training materials focused specifically on using catalog views, but I think it's a good idea.
