With the Centralite units I have, most of the config like temp floating point and setting what is exposed is done on the thermostat itself (the OEM manual covers how to set it up). zigbee2mqtt seems to have way more configuration options than ZHA in HA, both pick it to varying degrees.
I would suggest going the z2m route, as that would probably give you the most ecobee similar options: https://www.zigbee2mqtt.io/devices/3156105.html
This is what peak productivity looks like - after boot up, of course 😏
