For simple and stable and the uses you list, I personally would use
Amazon Echo
HomeKit (requires one iOS device)
Apple TV streaming box to allow access when away from home (it becomes the Bridge to the internet, list price $149 at Best Buy)
Lutron Caseta switches
Philips Hue Bridge
Philips Hue motion Sensors (these will work with Caseta switches via HomeKit and come in both indoor and outdoor models)
Optional: IDevices WiFi inwall Outlet (two independently controlled sockets)
Not the cheapest setup, but simple, reliable, easy to use, and excellent customer service from all 4 companies.
And there is a no neutral Lutron Caseta Switch (Not dimmer) that works with fluorescent tubes, although you may need to add a bypass device if the load isn’t high enough. Model PD-5WS-DV
The new free Alexa Guard feature will turn the lights on and off to simulate occupancy when you are away, but takes a few weeks to learn your habits, so that bit’s annoying. But once you’re out of the setup phase, works fine.
Amazon Guard Available yet? (May 2019)
You could also add some hue smart bulbs in table lamps. There are lots of third party apps for those that do simulated occupancy, and you could have the Caseta switches follow the bulbs via HomeKit as well.
Note: all of the above except the Apple TV streaming box also work with SmartThings, although you have to use IFTTT for integration with the iDevices in wall outlet.
