Subdivision not working as expected
Check if you have any overlapping vertices. If you look at the 2 other shapes, they are okay.
Select All with A, then press M and merge by distance.
Alternatively you may have some "Edge Crease&...

How to keep a smooth surface with sharp edges when subdiv applied?
Create this topology:
Bevel it:
Give it Array, Simple Deform and Subdivision Surface modifiers:
Also give it a Lattice modifier if you want to make it narrow at its top and bottom:

How can I Subdivide a Mesh into Even Square Faces?
No, you cannot fit perfect square faces on every cuboid. Let's take a simple example: a cuboid with dimensions that are not multiples of the same number. In this case, you cannot perfectly fit square ...
