Is it better to use landscape or flowers for new Chinese style screens?

It depends on personal preference.

New Chinese-style screens generally feature landscape paintings, or flowers, plants, birds and fish.

If the living room has a large space, use landscape paintings as screens. Such screens will give people a broader view and the layout will become larger.

There are also many choices of flowers and plants, such as peonies, roses, and lilies. There is a pleasing feeling that makes people feel better.
