Thanks David,
The explanation of 'at time zone' explains what I'd missed there. Much appreciated!

This is the solution. The timezone setting isn't a “server setting”, it is a session-local setting with an initial value based upon server configuration. Change it for the session to UTC if you for some reason must output +00.
The at time zone operator outputs a timestamp without timezone and that is why those variants don’t produce any time zone offset.
