Hi John, welcome to the forum!
Are you aware that you have selected WiFi devices as well?
One of them has a Tuya stamp and those are cloud controlled devices.
There is a way to integrate them locally but…
If you do a search on the forum you will see a lot of topics about these devices and many pro’s and contra’s.
I had some but ditched them.
Regarding zigbee: there are 2 different integrations (ZHA & zigbee2mqtt) to integrate them into HA.
If you take a look at Zigbee2MQTT you get an idea about what works with the z2m integration.
Also, have a look at this extensive guide: Zigbee network optimization: a how-to guide for avoiding radio frequency interference + adding Zigbee Router devices (repeaters/extenders) to get a stable Zigbee network mesh with best possible range and coverage by fully utilizing Zigbee mesh networking
I would advice you to start slow, read a lot, ask and gradually add devices/functions to your HA.
