I just wanted to follow up to my post from October 2019.
I just installed CentOS 8.1 and my WIFI card is now detected and works
properly!
So I'm a happy camper again, I guess I just had hardware that was too
new and CentOS 8.0 didn't have the driver for my WIFI card but CentOS
8.1 *DOES* have it.
Good thing, Both RedHat and DELL says it is "completely supported".
I was seriously thinking about sending the hardware back to Dell to
reorder a configuration that worked, but now I don't have to, there is
now driver support for the Intel AX200 WIFI card.
I just had to unexpectedly wait a few months.
