I still enjoy my little Edgerouter-X SFP, it's fast, compact, power efficient and I can plug my fiber internet connection straight into the SFP slot. Management can be done via SSH. What's not to like?
Edit: and yes, I know the edgerouters are still listed in the ubnt shop, but they have been 'sold out' for the past 3 years now. I don't think they'll ever return.

Another option if you don't need tremendous performance is https://pcengines.ch/ which also runs OpenBSD very well.
Immediate experience has been so so - the router kept rebooting every 12 hours - had to disable the AX interface and keep it wired only. WiFi is currently coming through a Netgear AC access point, which defeats the purpose of the system. I'm thinking if I should switch manufacturers before I get in too deep...
