What file holds all those settings, now? As a rule, I prefer to edit text 
files to finding the right GUI/TUI utility to muck with them. I'd also like 
to know how the new and old files interact.

The same config files are in /etc/sysconfig/network-scripts (the
supported options may vary some).

Thanks. With that clue, I found this more complete answer:

<https://unix.stackexchange.com/questions/483354/rhel-8-deprecated-network-scripts>

So the settings are in the same place but the scripts that parse them are 
gone or not executed by the new system, including *-local. Anything in the 
network-scripts RPM is gone. nmcli and friends replace that.

The "network" systemd unit is replaced with the NetworkManager unit
when
starting/stopping the whole network system. More about that here:
