I used to be a big pfsense fan, but Ubiquiti's UniFi is my jam now. If you get their gateway, PoE switches, and a couple of APs, it's by far the best SoHo system I've ever used. Enterprise features that are easy enough for non-network admin technical users to figure out, auto firmware updates, rock-solid reliability, all for around the cost of a high-end "gaming router" that will crash weekly.
