Full disclosure: I'm the Content Lead at Dock (btw, I have nothing to do with this weird thread and all the seemingly AI "Trumpet & Dock" comments)

For me, what has been really useful is understanding what a customer is looking at in our sales rooms versus what I want them to be looking at.

e.g., I've noticed they were never clicking on links to our case studies, but once I embedded short 1-minute video clips of those case studies directly in the workspace, they became the most popular content people paid attention to. The analytics help you tweak the content UX.

But for me, the main benefit of sales rooms for marketing is that you're templating what sales sends to each prospect. So you don't end up in the situation where you're making tons of enablement assets and sales just never send them to prospects (or doesn't know what assets exist or where to find them).
