Thanks for the tip. It did help. See below.

I did an apt purge varnish, then reinstalled a new, then copied the
unit file like you recommended, and varnish did start successfully.

I made the changes in the unit file (different listening port, a
different varnish vcl), then systemctl daemon-reload, and it did start
this time.

Doing things differently is mildly annoying, but can be tolerated.
Having no diagnostics to go by at all is another ball game.

Thanks for your help.
