I use FreshRSS which is hosted on my home server. What it does is allow you to categorise the feeds and you can also do some further things like hiding them from the main feed if you choose to. Then beyond that it pulls article tags from the original sites which you can search or predefine a filter for and you can also label individual articles you find. What it can't do unfortunately is allow multiple tags for a site to be applied, so its not possible to classify content from a source multiple ways and have it surfaced in multiple places while only having it shown once and read once. You can put a site in multiple categories but reading it in one place wont read it in the other.

It is one of the better systems I have used, its by no means perfect but its fairly quick and easy to use with some decent shortcuts for working through the sites and I manage hundreds with it and it happily works across every platform since its a website.

+1 for FreshRSS. Use that with NetNewsWire[0] as a client and RSS looks very nice.
