Ok, that is a little confusing. The nmcli "managed" means that
NetworkManger is handling the device. The iwconfig "managed" is
referring to the mode that the wifi device is in.

That can't be the actual command you ran, because it's not valid.
You're missing a "dev".
I hear what you're saying, and yes, the man page says you should have a 'dev' in there,
but that doesn't make any difference"
[root@localhost fhew]# iw dev wlp2s0f0u4 set monitor none
command failed: No such device (-19)
command failed: No such device (-19)

Yes, that seems very likely to be the reason for both those commands
failing.

I started this journey with a variety of web pages such as this one:
I'm not wedded to this USB adapter, I'd like to know which one would actually work
in monitor mode, out of the box, with Fedora supplied drivers.

When you open the capture options dialog, you might need to scroll to
the right to see the monitor checkbox.
Nope, I tried sending a screen shot, but the mailing list is holding my message for moderation.
There is a column in the table entitled Monitor Mode, but it's filled in with dashes.
