I have to say that a farm pond would be my favorite choice. It is nothing fancy but I tell you one thing it is definitely private. The value is the complete control of the eco-system. Whether you are going for brim or bass you as the owner have the complete ability to choose.
The other part of the equation is that it is completely your choice. You as the owner can be the last line of defense in what is to be swimming around in your very non fancy type pond. Up keep is minimal and the dividends are somewhat controllable.
If I were a novice I would certainly determine which species live in harmony with each other.
