The ESP32 is very overpowered for random home projects. But the cost is low, and they can be used with the Arduino ecosystem which is very beginner friendly.
Often the ESP32 is far cheaper than whatever sensor you're making it monitor. WiFi isn't the perfect technology to upload sensor data in the home, but anything proper Zigbee is more expensive and more complex to use. So the ESP32 ends up in all kinds of projects.
