I've been doing home automation for many years.

From what you described, using Home Assistant in the center would be the way to go (works fine on a raspberry pi, in the beginning at least)

For the devices, I mainly use zigbee sensors and lights etc. and bunch of fully DIY stuff running mostly on ESP32 with ESPHome.

For the starters, you can skip the zigbee devices all together and experiment with Home Assistant + ESPHome

Note that the rpi is way overpriced for what it is currently, just get a mini pc with real storage, unless you need the gpio

M5Stack (https://m5stack.com/) could be a good starting point, especially if you do not know exactly what you wanna do.
