Same here, when I was getting started I bought some wifi light bulbs, realized they expected you to have them connected to the internet and immediately returned them, instead getting zigbee ones. Has been working for years with zero issues, was great when Philips started going cloud focused for their Hue bulbs since I didn't have to worry about it affecting me.
I bought a bunch of zigbee light switches years ago. A couple of them have failed and I replaced them with dumb switches. For my use case I found I was rarely using them as anything other than dumb switches anyway.
