I’m tired now, so I will let other people continue the conversation. But just very quickly.
Phillips hue used with the Phillips hue bridge Are excellent devices. I use them myself. But then they form their own mini network with the bridge and do not act as repeaters for your other zigbee devices.
Ikea Tradfri Bulbs do not have quite the same color range, But are much less expensive and are still good bulbs. They can be used either with the hue bridge or directly with a smartthings hub. And when used without the hue bridge they are excellent zigbee repeaters. There was much discussion on this in the forums, so just look around.

All of the smartthings brand sensors are Zigbee, not zwave. You had them on your list.
