Thanks for the explanation.

Does that mean if I install Fedora using 'linux scsi' then it will use
an initrd with scsi drivers installed in the image ?

AFAIK it should.  Maybe someone with experience will chime in, but try
and see. The worst that can happen is it fails again.

I cannot be bothered to do another install.

What I found very off was doing a full install then ending up with a machine that will not boot after UDEV, very disconcerting, all because of a missing scsi on the startup line.

Why the machine hangs when a scsi card in inserted but not installed I do not know.
