Many here hate to hear it, but vinyl (uninsulated) is the most durable commonly used siding material. It performs well for a building envelope because it creates its own rainscreen.

Engineered options should be installed on rainscreens to get durability that competes with vinyl. I would use LP Smartside before Hardie but Boral TruExterior is my current favorite as mentioned in this recent [fascia thread[(https://www.houzz.com/discussions/metal-clad-fascia-dsvw-vd~5494825?n=14).

I would avoid stick on stone and be careful with any masonry choices. For real durability in wet or humid climates, masonry requires better craftsmanship than what you see with current construction practices.

I'm very happy with the prefinished LP smartsiding I used.

I know you didn't ask but consider a door on the flex room from the kitchen area.

Here's some new info.-

More products with integrated rainscreens. No caulking needed.

We are very happy with our LP Smartside. We have no brick or stone on our house and it looks very nice. Is the floor plan set? Having the bathtub and the laundry as the focal points of the main passage through the house is not good. I recommend deleting the laundry door by the master bedroom - will also give you more usable space in the laundry. Your dining area is very narrow - if you allow for 36" on either side of the dining table and room to push back the counter stools, there is not much room left. Your roof pitch is very steep - unnecessary expense.
