Can someone please explain with a scenario for each tree structure why it is chosen over...

Take this with a pinch of salt:
B-tree when you're managing more than thousands of items and you're paging them from a disk or some slow storage medium.

In a B- tree you can store both keys and data in the internal/leaf nodes. But in a B+ tree you have to store the data in the leaf nodes only. Is there any advantage of doing the above in a B+ tree? Why not use B- trees instead of B+ trees everywhere? ...

Possible use of B+ tress is that it is suitable for situations where the tree grows so large it does happen that a B+ tree is used even when it in fact fits into memory, and then your cache policy is a separate from B+ tree maintenance....

Most database products use some form of B-tree (eg B*-tree) to manage their external data.

If I understand it correctly you're talking about building a tree structure that would give reading in your tree structure, but subsequent lookups and traversals of the tree would likely be quicker than hitting disk storage each time....
