I really like Lutron switches and use them in my own home. I don’t think they have matter support yet, though: they use their own SmartBridge instead, but since right now it works with pretty much every other platform, including SmartThings and Apple HomeKit, it hardly matters. They do belong to the third-party standards, organization for matter, but I think they are still waiting to see what happens.
As far as Matter options, I agree that right now the Leviton matter over Wi-Fi are probably the best choice. (As I’ve mentioned before, I myself only use devices with good safety certifications if they’re going to be wired into the mains so that leaves out most of the Chinese brands.) Kasa and Tapo do have some, but reviews aren’t great yet.
There are a number of brands which are promising matter over thread switches, but other than Tapo I don’t think any of them are available yet.
So it’s a little early to look for those yet.
As far as zwave, that’s a whole other discussion. Z wave uses a different network addressing scheme than “IP“ which is why it’s more difficult to bridge zwave devices then Zigbee or thread. Not impossible, but no one’s signed up to do it yet. Silicon labs, the chip manufacturer for Zwave, does have their “unify“ project, which would put Zigbee, matter, thread, Bluetooth, WiFi, and Z wave all on one chip, but as far as I know no one signed up for that yet, either. So it looks great in theory, but it hasn’t happened in reality yet.
If you look at Z wave without matter, I do think it has a future. See the following discussion.
