Most fruits can be frozen, simply by cutting up and freezing.
However, you may find they will be softer and may slump when thawed (eg. strawberries, raspberries, plums etc.).
Also, with a lot of water/juice created.
Melons will keep their shape fairly well, though may be softer in texture and create some juice.
Cabbage can be frozen, blanched or not.
When I want to freeze something, but unsure ... I try a small "test" when I have some on hand. That way I haven't done a lot of work or gone to a big expense, if I do not like the results. Leave it in the freezer for a couple of weeks, and then take it out and see how it "performs" and make your decisions.
And yes, Google, can be a your best friend for more info!
