> It seems like either one evaluates the contents of the `box`, and would only make a difference if you tried to use `x` afterwards?

More or less. x^ moves the whole box whereas x* copies the contents of the box.

> Awkwardly, it also hasn't been assigned so I'm not sure the box is accessible anymore?

Yes, if you move something and don't assign it then it gets dropped, same as rust.
