I love the form factor and LED ring of the Fibaro Smart Plug!
Not a fan of the Z Wave setup, though. Do you happen to know if the WiFi version works properly with an Android app?

I previously had TP-Link HS110, which is WiFi only, that might fit your needs. I wasn't a fan of the Z-Wave "mania" either. But I am more than happy with HomeAssistant, it's fully customizeable to my needs. I have a couple of smoke and various other sensors that all integrate into HomeAssistant.
EDIT: You can also connect the TP-Link to HomeAssistant, it supports all kind of devices, see
