This looks OK to me so far.

Can you take a look at the bootup logs (journalctl -b -u NetworkManager)
and see if the 'ifcfg-rh' plugin reported any errors for ifcfg-internal?

NM *should* show ifcfg-internal here too, so we get to figure out why
it's not doing that.

ip link is reporting the actual network interfaces on the system, but
"nmcli con show conf" reports network configurations/profiles stored
in /etc.

The closer match to "ip link" would be "nmcli dev".  What does that say?
