Firewalla, Pretectli, and plenty of Amazon/AliExpress vendors sell little mini PCs with a bunch of ethernet ports. I use one running NixOS as my home router.

Re: wifi cards, I've not seen any wifi cards that seem like a suitable replacement to a dedicated AP. I just use a consumer Asus router in bridge mode instead of router mode.

One thing if you go with one of those random Amazon/Aliexpress pcs is ditch the power brick they come with. Those generic things are stupid under built and inefficient. Get a proper matching one from a brand name like Mean Well, Delta, FSP, CWT, Adaptertech, Lite-on. Really important if you’re running it 24/7.
