...I would avoid the hardie board or any wood type material and try to find some thinner plastic material for the other doors, hopefully switching screws will help a little.

"Hard board" or HDF (High Density Fiberboard) or Masonite is not waterproof and barely water resistant.
That said, it can be water proofed with any polyurethane coating.

On the other hand "Hardie board" or "Hardie Plank" is already fully water proof as it has no wood fibers in it.
It is purely a formed cementitious sheet used for tile installs or exterior siding. The only downside of using Hardie Board would be the etxra weight added to the door.
