     1).    Why is it producing the messages "Updating and loading repositories:"and "Repositories loaded." with nothing between them which means that it didn't do anything? This functionality is independent of whether the command is issued under sudo or not.

If it hasn't been long enough since the last time it checked the repos, then it just loads the cached data.  You can override that with the refresh option to force it to check.

     2).    When it does list repositories between the two messages, what is it actually doing when the command is not issued under sudo, particularly when issuing the command lists the two updates repositories and then issuing it again immediately after produces nothing between the two messages?

If you don't use sudo, then it saves the cached data somewhere that your user has access to.  I don't know where that is, but why would you want to do that anyway?

I'm not explicitly doing it, it's just that sometimes I forget to use sudo and dnf then goes off and does whatever it does for this command instead of prompting that it needs sudo to function, like some other software does.

It doesn't need root access until it's affecting the system state. As a user, you can query the repos and download packages, but no install or remove.
