Just to report back on this in case anyone finds this comment in the future... standalone mode almost worked.
On the UniFi U7 Pro, standalone mode was limited to 40MHz channel width on 5GHz and 160MHz channel width on 6GHz, which was a dealbreaker for me. The hardware is capable of 240MHz on 5GHz and 320MHz on 6GHz. So, I installed the controller on a local server and used that to configure the hardware to its fullest potential.
