The zwave alliance website does a great job of keeping everything up to date, but the similar zigbee alliance list, unfortunately, is rarely complete.
The quirky outlet should be fine, as I mentioned, a number of community members have it. And the smartenIT was on the original “works with smartthings” list and should also be fine. SmartThings went through a couple of iterations where they dropped things off the list, in some cases just because they didn’t provide the right size photographs of their devices. But I haven’t heard of any situations where the SmartenIT device wasn’t working.
I’m not familiar with the Orvibo one, but based on the description it should be fine. Quite a few community members used their in wall micro, which is no longer available.
