This one is more or less comparable I believe. No idea about FOSS though, if it’s important then my advice is invalid, of course. But if I personally was going for a FOSS router, I’d just get an old-ish computer with several NICs inside and install some BSD on it.

If all you need is a router, Mikrotik also offer stellar support, lots of configuration options and are much cheaper for the same specs.

UPS depends on usecase and on the stability of your electrical supply (which varies greatly from place to place). I just leave everything running and have it configured to restart automatically on power restore (if it fails, which it rarely does).

every day we stray further from god
