I selected "Maximize Panel" using the Cashew and the plasma menu. This works.

But when I log in using an X server with another display size, e.g. via an X-terminal, another computer (X -query myhost) or NX, and this other display has a smaller size (x or y depending on the panels orientation), then the panel will no longer be maximized when logging in using the original, bigger size in a later session.

The setting "maximized" should be remembered as such, and being applied on every new start of plasma.
