That’s a very valid use case! We’re currently working on adding a new “Query block”:
https://github.com/WordPress/gutenberg/pull/22199

Like you described, the idea is to provide extra functionality (queries) to the post block. I don’t believe that is ready yet.

In the meantime, you can certainly give other plugins a try. I don’t have any personal experience with any, so I wouldn’t be able to recommend one :).

Hope this helps!
