re: Home Mesh Wifi

I've tried to read this whole thread and understand more than I did before I started. Couple of questions:

Are the fully wireless, or wired backchannel systems better at switching between wifi units than full wired/AP's?

(Please let me know if I'm asking the correct question here)
I want to have whole home wifi as well as control of anything I put in the house in the future. As in lights/outlets thermostats. I am new construction so I can wire all the ethernet I want.

What I am finding is that zwave is the most widely standardized platform for home control, so I'm looking for a system that will give me whole home zwave.

It looks to me that the Samsung Smartthings system would do this. But most of the reviews say that it doesn't seem to do it very well. And it looks like it would take 4 pro units to do what I want to do. ($600)

So I guess I'm looking for a system (imagine a large T shaped home) with a central hub, and 3 wired Access points at the tips of the T, but with zwave/zigbee access across this whole area as well??

Or am I overthinking the automation stuff and I should just go with the well reviewed velop system, and add some z-wave hubs?
