 Not quite responsive:
1) I do not want to invent a MAC address, I want to tell it to use the manufacturer's supposedly unique default address AFTER the OS/driver/network-manager/whatever has already wiped it out during the boot process. Your command example assumes that I know what it is.
2)As you can see in the subject line, I am running Fedora, not rasp(b)ian. Even if Fedora's GUI does not work on the RP4, I would rather run headless than have to learn Debian system management after a decade of living in RedHat world.
 

Unfortunately you are probably the only one here that is using RedHat on a Pi.
AFAIK, ethernet defaults to 'one permanent MAC address' - its only wifi that tends to switch around for security in public wifi spaces.
Have you actually checked to see if you are getting ethernet randomisation?
ifconfig -a will display it
