OPNsense is decent too. Problem is that running anything open on those AP will still be a mess unless they support something like OpenWRT ;)
Separating router from the AP was something I considered too for building a 10 Gbps network, since I haven't found any WiFi router that could also handle 10 Gbps wired without some accelerator chip requiring non upstream mess to work.
