Funny you use light switches as an example because I have indeed spent some hours looking at light switch options. Decided not to blow a bunch of money on smarthome stuff (yet…), but for anyone who likes to tinker with that kind of thing the Inovelli switches look pretty fun. Time well spent? Who knows. But I know more about smart light switches than I used to!
Something else I think about a lot. I have Lutron Caseta but would probably choose something Z-wave if I were starting from scratch today. Proprietary stuff is generally not as flexible as the more open-ecosystem stuff, but Caseta works perfectly with Home Assistant. The worst part of smart lights is how I've forgotten the tactile sensation when flipping a light switch. Sometimes I see regular light switches outside…
I don't like their weird button pads, but more recently they also come in a normal looking rocker version. Don't know how tactile it feels but I would bet nicer than the original Caseta controls.

Inovelli makes a Z-wave version (red series) as well as a Zigbee (blue series) which is supposed to support Thread/Matter eventually. Among other things, they can operate either as a switch to turn off a circuit, or in "smart bulb mode" where the circuit stays powered and on/off commands are sent to the bulb.
