Assistance with Zigbee Thermostat Search

I am looking for a zigbee thermostat. No, not using zwave thanks. I would try Wifi in a pinch.

I tried the compatibility list - but of the choices, most are 'not available' and the other ones seem to connect indirectly (HA etc). I used to use a Centralite and it was perfect, but it was left behind in a move.
I have forced A/C and Heat, brand new system. I have G, W, C, Y and RC connected currently to a Honeywell Home unit (not smart sadly) using wires Grn, White, Blue, Yellow, and Red respectively.
I keep seeing Xfinity units with the word Centralite and the price is a 1/3 of all others but that just scares me. I've always paid about 80-120 for thermostats over the years (this is I think my 3rd. I did a zwave unit before but past is prologue.)
so. knowing its a boring thread - anyone with a simple 'this.' and I'm good?

You don't make it clear why you have the opposition to Zwave, but I would take Zwave over IoT wifi to keep things local. The Honeywell T6 Pro Zwaves are very popular, and they are rock solid for staying connected and responding to commands, at least for me.

If you are going wifi, stay away from Honeywell. They limit their API calls and updates are slow. I dumped my Honeywell wifi thermostats when they started taking minutes to update locally after a setting is changed via the cloud integration. Maybe other brands still do instant cloud updates, but you also lose local control and gain an internet dependency.
