Another stuff I see missing - I can see there is "monitoring" on paid instance. But I don't really know where to learn what exactly is it about. Its crucial to understand memory / cpu consumption of your jobs with time to place them right, so I guess (hope) it's that?

We should probably clarify what we mean by monitoring on the home page. That currently just means "we have numerous health checks that do Orchest introspection to see if everything is operating correctly". We don't expose a dashboard of compute metrics at this time. It's a good idea and something we could add as we progress. We'll make a note of it.
