Its not for everyone but I use Cisco Aironet APs with a virtual wireless LAN controller. Ubiquiti is popular among the community. They’re cost effective and work well in a home/small business environment. Aruba InstantOn are decent as well from my experience, but they’re cloud managed and this is self-hosted after all :)

I’ve extensively used Cisco, Meraki, Fortinet, Cambium, Aruba, Ubiquiti and Juniper in a professional setting. Avoid Fortinet and Cambium APs if you can, my experience is that they can be pretty unstable.

Generally speaking if you’re going to have multiple APs, you’ll want something that’s centrally managed so the APs are able to be aware of each other and manage clients effectively.
