The GL.iNet Flint 2 came highly recommended (near cult following) from my own pretty extensive research for offboarding ubiquity. It comes with a OpenWRT fork pre-installed, but flashing mainline OpenWRT is officially supported. I've been happy so far.

The Flint 3 just launched, and the headline feature is WiFi 7: that should be less of an issue if you're going with separate APs.
