Back to helping OP.
I would use ordinary switches as much as possible. I would not eliminate ordinary switches people understand how to use.
IF you really need a display device like this, I would stick to an Android tablet in strategic places around the house. They are inexpensive, larger, and can be mounted at eye level instead of belly button level.
I have a tablet in my kitchen just for Hubitat, the hot tub, grocery list, and a few other oddball things. It might seem cheesy, but I put mine on Velcro Command Strips, so I can use the tablet elsewhere or while walking around making my shopping list. Easy on and off the wall. I even semi-automated mine, the power outlet is controlled by motion, no lock screen, and the tablet wakes upon power up. So when I walk into the kitchen, the tablet wakes like magic.
