I like Mikrotik for routers. They're cheap and have a lot of knobs in the SW (maybe too many if you just want NAT). They do run linux, but their SW isn't open.

I've been pairing my Mikrotik hEX with a Unifi AP. Not sure what I'll do going forward, as I've heard Mikrotik's APs aren't as good as their routing and switching hardware. If I was going the "dedicated machine" route, I'd probably go with OPNsense nowadays.
