Odroid H3 is pretty good. Bought one myself as my (yet to be fully operational) home router.
It's small, quiet and has 2 ethernet for WAN and LAN and you can plug in an official USB Wifi dongle addon and it's good to go as a router.
You need to pick a few addons from the bare machine, like memory (I went with 8GB to run many containers), ssd (I went with m2 instead of emmc) and a case.
It's x86, so you'd have maximum compatibility for architectural differences.
