I'm running 6th, 7th and 8th gen nucs, all i3s, in a cluster with about 9 vms between them. I've run plex and jellyfin off of both the 7th and 8th without any issues. I've only had two transcodes happen simultaneously since I don't really share my server outside of my household but based on usage I don't think 3 would be an issue.
If it was me, I would be looking at an 11th gen i3 (tnh-i3000 I think). The taller chassis models have space for an m.2 and an SSD so you can mirror your drives, have 2.5g Ethernet, and have add-on modules to add another 2.5g port.
