2/3. Lutron uses a proprietary wireless implementation so it can't interoperate directly with Z-Wave. The Lutron SmartThings has an integration with Lutron hubs so the ST app can control Lutron switches. I think Homeseer has a Lutron plug-in but you'd need to double-check it. Lutron works with Alexa but I don't know about Google Home.
jus4. I'd say the big advantage of Lutron over Z-Wave is reliability. Lutron has been using their wireless protocol for a long time and, since it's proprietary, they have more control over the devices. The bridge says 30' range plus one extender with another 30' from it but in real life, people don't seem to have many range problems. However, Caséta isn't intended to be a solution for large houses. The big disadvantage is the switches tend to be more expensive and there are fewer options compared to Z-Wave.
I use Lutron Caséta for my wall switches, Hue for my colored lights, and SmartThings/Z-Wave/Zigbee for my sensors. No regrets on any of those choices. I've not tried the Lutron-SmartThings integration as I use Apple Homekit for my device control (with Homebridge for SmartThings-HomeKit integration) and Alexa for voice command.
