Some time ago, maybe a year or two, I tested NomadBSD once again and my internal Wi-Fi device was not supported at that time. I used an ethernet/wifi bridge and was connected with my 2,4 GHz Wi-Fi. The data speed was around 10 Mbps.
Now, my Intel AC9560 is supported in FreeBSD. I can connect to my 5GHz Router. But the data speed is only 20 - 25 Mbps. With Fedora Linux, I have much, much more. That driver seems to work better.
For testing, I activated Wi-Fi and ethernet parallel to see what happens. It’s curious. Now I get a speed of 65 - 75 Mbps. 
From now on, I use both together devices to get the most out of the network.
