And yet you insist the pulpy (not fleshy) fruit of a banana is a berry
when in fact it is not.

A banana is berry by default, it is not worthwhile to come up with a
different term. Since plantains are eaten more or less as vegetables these
support the thesis!

The classical definition of a drupe is that it is a one seeded berry.

By "classical" you mean the ancient Romans? Or maybe the Greeks?
+ + +

Having a woody stone endocarp surrounding the seed has nothing at all to
do with the definition.

+ + +
That is only because you are using the "classical definition". If you were
to look at contemporary definitions you would find otherwise

If the fruit has two seeds, it automatically becomes a berry by default.

+ + +
Nope. It is less and less surprising you are confused about bananas.
+ + +

So what about those plants that have fleshy fruit with 1 to 3 seeds in
them?

+ + +
Depends on the presence of an endocarp. Easy, isn't it?
