I've helped lots of people with home automation Network build outs l; the biggest factor is the RF environment.
If you're fortunate enough to not be battery constrained at most endpoints and can put a high quality Wi-Fi access point in an optimal location than Wi-Fi is incredibly reliable.
The tooling for inspecting all layers of a Wi-Fi network is infinitely more accessible and mature and that certainly helps; I can't go to My local big box store and get a USB thread dongle for 20 bucks that will just work on a Lennox computer and integrate nicely with Wireshark out of the box...
I have a Unifi home network with two Wifi 7 access points and gigabit ethernet. For home automation, I went with ZWave and do not regret it at all. It's been rock solid and I've never felt the need to get a dongle to debug the traffic. I don't want to be working through all of the WiFi baggage with my home automation devices. I recently introduced some Zigbee bulbs (hue and cheapos from Amazon) and they've been mostly "fine", albeit with lower range.
No, you have to order it from Mouser for $16 instead.
