Or, a quick look at the docs

No, it is in fact the first form. Note that the link must be down before
you can change its MAC address.

Also if you set this to a non-default value, “ip link show” will show that
default value as the “permaddr”. So you can easily set it back to that.

 Running headless, using ssh to login, I cannot use an interactive command to do this. Does this information live in a configuration file somewhere under /etc?
And the difference between raspian (a Debian derivative) and Fedora (which uses systemd) *does* make a difference.

After logged in with SSH, you *are using* an interactive command.
The distribution should not change the systemd setup. The configuration
files are in /lib/systemd/, /run/systemd and /etc/systemd. Please get
the systemd documentation and read it. The network setup is in network
subdirectory in the three places.
On a Raspberry, the hardware MAC address is probably b8:27:eb:xx:yy:zz.
Please post what the first octet (b8 above) is.
