I would say you're looking for a basic conflict zone between sub-factions? Did you check mostly Independent Systems? You can always check Powerplay systems that are Preparing, Fortifying, Expanding but it sounds like you are looking for an Independent system with a basic conflict zone. That's hard to judge though since it looks like you are actively participating in powerplay. The Vulture jump range is laughable so scouting for a conflict zone might not be easiest in that.
With the BGS being updated I also hope to see the ability to search for systems that have opened a conflict zone between sub-factions.

I think Ochoeng has a conflict zone right now, haven't checked since yesterday. Also has rares and CG. I don't really think another post was needed but I agree with you on the fact that the system map should include data on whether there is an active conflict zone or even list if the system has a High Resource Extraction Site. It would encourage players to make a route checking these places for other players activity if they are Pirating/Bounty Hunting and if it really became a problem you could just pop into solo.
Edit: Wow really 12,542 to choose from I didn't know that but I don't read Galnet as much anymore
