Do a Zigbee setup. You'll need something like Homeassistant which you can setup on a home server or raspberry pi (there's tons of tutorials). Or buy a pre built little plug and play one. https://www.home-assistant.io/green

You'll also need a Zigbee radio. Homeassistant sells one https://www.home-assistant.io/connect/zbt-2/, but I use a network attached one like https://a.co/d/0aQpLciK

For bulbs the highest end Zigbee ones would be Phillips Hue (which yes work with this setup - you don't need their proprietary hub). But they are stupid expensive IMO. There's a brand called Innr which are half as expensive and just as good. If you want a more budget friendly one ThirdReality makes bulbs which are perfectly good but maybe not quite as bright or good on colors as Innr. I have a mix of both, but try to keep them in separate rooms so you don't notice the slight color difference.

You'll also want a Zigbee switch. I rent so I can't replace the wall switches so I just stuck on these battery buttons by ThirdReality. and covered the switches with 3d printed covers. The batteries last a year or so with a AAA. But there's also ones that completely replace the wall switch like https://a.co/d/01w5jj63

And now that you've got Homeassistant you can do other cool things. It can hook into basically any smart devices. When I press and hold down on the light switch/button in my living room it turns off all the lights/lamps and the TV at the same time. Or the one in my bedroom also controls the fan by the bed. You can get motorized curtains that can help adjust light levels automatically and close when you're away to insulate. You can hook into motion sensors, weather stations, door sensors, humidity sensors, etc. There's also Zigbee smart plugs so you can control really anything.

It is a bit pricey to get into but once you have it you own it, and no company can just shut down and leave you SOL.
