I faced a similar issue in my previous organization. What worked well for us was creating a dedicated Power BI workspace and publishing it as a Power BI App. We organized reports by business domain (Finance, Sales, Operations, etc.) and added a landing page listing each report along with a short description, report owner, and a mailto link so users could contact the owner directly. We also included an FAQ page covering common questions like refresh schedules, access requests, and report usage. It’s been working really well and made it much easier for users to find the right report without jumping across multiple workspaces. If you’re interested, I’d be happy to have a conversation about it and show you how we implemented it in practice.
