I know the paradox, this simple exercise doesn't
support your view.

Yes .. it does. If the pole was not taking up less
space in the barn's frame of reference, it would
not fit inside the barn.

There is no "barn's" frame of reference. In the rest frame of
the barn, an observer in the front of the barn and an observer in
the back of the barn will not agree that both doors were closed
"simultaneously". It is very important that you not imagine you
can have instantaneous signalling from the front to the back of
the barn.

The pole is "really" contracted, AND it is entirely a matter of
perspective.
