report server structure

Hey guys,
how does your organization keep all the reports structured published on the PBIRS on-premises?

We are kind of missing tag options to tag different subjects to a report. Also we want to assign which department is responsible for a report (not who changed it last).

We tried organizing by folders, we tried it by strict naming regulations but neither really worked out for us.
How do you guys make reports easy to find for your users especially if many reports are assigned to this user?

Thanks for your help!
