I bought a few of the Feit dimmers from Costco and converted them to Tasmota using tuya-convert. I haven't tried any of the others that you mentioned.
After that, I loaded up a version of @mhutchy 's Sonoff basic driver that I modified to add the dimmer functionality.
So far, so good. And it's all local operation on my home network. No cloud integration required.
If you make the leap to Tasmota, you could try this set of firmware and drivers from @markus. I haven't used those so can't vouch for them yet, but other people in that thread seem to be all good.
Of course, all of these require applying unsupported firmware that can't be rolled back, so use at your own risk. But they were cheap enough and I enjoy the tinkering.
