I have a pretty similar hardware setup but I went for a used Ruckus R610 WAP. With a PoE injector and shipping I spent around 200 USD. I'm really happy with it. My current goals are proper IPv6 support in case the day comes where my ISP will no longer give me an IPv4 address. The setup is currently close to perfect, but my DDNS service (google domains) isn't letting me make dynamic AAAA records for some reason. I'm in talks with support right now. I also have not successfully made ip6tables entries for rerouting IPv6 DNS traffic to my local DNS servers. When I have made entries it totally breaks IPv6. I too would prefer an x86 box for a router, but OTOH purpose-built routers are much more energy efficient. Heat is bad for reliability and more power means less run time on a UPS. My next home network purchases will be an all-flash TrueNAS box that is backed up to Backblaze. I want to get off privacy-devoid cloud services.
