I would recommend checkout out the NK 6.0 build. LGA 1511 is the current sweet spot for performance vs cost.
Modern single core systems will offer better performance for most home server use cases. For most use cases higher single thread performance will be more important than more cores unless you have a use case that involves running many VM simultaneously or you have some application that is very compute intensive and very parallelized.
As @faspina pointed out AM4 does offer an excellent value in terms of compute performance / cost, however if you are interested in transcoding video in Plex or Jellyfin I would recommend sticking with Intel since Intel’s QSV video transcoding acceleration is significantly better than AMD for which video transcoding is a bit of an Achilles heel.
