To be pedantic:

• newcomers are Thread and Matter, based on IPv6 and include standardized device profiles that should really help things work together. The standard is widely sponsored, including by Apple and Amazon
• Matter works on your regular ethernet or WiFi network, and can access the internet. This is likely used by things permanently wired to power. For example Apple HomeKit uses this to control devices like light switches or printers
• Thread is a local low powered mesh network, sometimes called Zigbee 2.0 because it’s the same frequency and comes from the Zigbee Alliance. It is very suitable for battery devices like lightbulbs and sensors, and is bridged to Matter for controllers
