Definitely Zigbee or Z-wave instead of wifi. Once you start to build out more devices you will be glad to not have gone down the wifi route.
I went with Zigbee and have Sonoff SNZB-02 temperature and humidity sensors in each room that have been absolutely flawless since the day I installed them, and they last about two years on a single battery!
I would obviously recommend them but I don't have any experience of other thermostats or of Z-wave.
I did also install smart Zigbee TRVs on each radiator but I don't rely on the internal thermostats of them as they don't accurately represents the overall room temperature.
I run Immich, along side about 10 other services, on my DS420+, and it runs great imo. The initial import of all my photos (40,000+) did take a long time but now that it's up and running it's more than quick enough.
