Ubiquiti unifi has struggled to integrate routing as reliably and as well as the wireless and switching piece. Mikrotik router and unifi everything else has kind of been my go-to for at least 10 or 12y now.
I can't speak for the more "entreprise-y" unifi stuff but the routing on the ubiquiti gear i've used is actually just FRR and if you SSH in you can do a whole lot more than is surfaced through the UI - for example, I have VXLAN running on my UDR7 right now.
It's not something I've tried but I imagine you could actually expose FRR directly and configure through that
