Matter over Wi-Fi in an A19 body. Pairs to HomeKit, Google or Alexa with the code on the box.
Lighting is where smart home buyers get burned most often, because almost every bulb claims compatibility and almost none states how it dims. A bulb that jumps from 40% to 45% rather than stepping smoothly will make a room feel cheap, and that behaviour is not visible in a product photo.
The listings here state the protocol on each product: Matter over Thread where the listing says so, Zigbee or Wi-Fi where it does not. That distinction decides what you need before the first bulb works. Thread bulbs pair directly with Apple Home, Alexa or Google given a Thread border router. Zigbee bulbs need a hub. Wi-Fi bulbs need neither, but they occupy your router and depend on the vendor cloud for remote control.
Strips and ceiling fixtures add an install question that bulbs do not: where the power comes from. A plug-in strip is a five-minute job. A ceiling fixture that replaces a switched light needs the wall switch to stay on permanently, which is fine for most people and unacceptable for some.
If you are lighting a whole room, buy one bulb first and live with it for a week. Dimming curve, minimum brightness and colour temperature drift are the three things reviews never capture and the three things you will notice every evening.
