Nest Hub Plugs and Bulbs

I’ve been looking for a way to have a touch pad on a wall or counter where I can just touch the screen to turn lights on and off. I see Wyze and Nest Hub seem to have partnered up.

Would I be able to control my bulbs and plugs from a single screen or would there be a lot of scrolling, swiping, and tapping?

Also, which cameras/versions will work or display on the Nest Hub? How many cameras will fit on the Hub screen?
