Looking For Interesting County Level Data Sets To Analyze

Hey All! During a project I created a script which collected all the neighbors of a given county which I now am looking to leverage to do some analysis. There should be a cool experiment possible comparing some features of counties who border one another but are in different states as compared to other counties within the state for example. Does anyone know of any interesting county level data which is available at that level of granularity which you could point me in the direction of. Im avoiding typical “Census” stuff since thats beaten to death by political scientists. I know surveys are hard to get at this level (most people just use MRP if they even bother projecting down that much), but what other sources can I draw from.

Is doesn’t need to be particularly clean as I can manage, merge and claw through but I am hoping for it to be detailed!

Thanks in advance!
