AmpliFi was not even on my radar. Thank you for suggesting it as an alternative. It looks like the AmpliFi Instant system: router + mesh point for $179 covers 4,000 sq ft. That is more then enough for my home. It also looks stylish:
I'm coming back around the idea of a meshed system because I can extend it later with more mesh points.
Not sure about needing a touchscreen display though. It is cool, but I'm hoping not to touch it all and have it just work. In fact, I would prefer less blinking lights at night if possible.
