Switch Control Button that looks like a switch?

As for the delay timer, Rule Machine will give you that functionality.

And for the switch, you can check out here:

SmartenIT ZBWS3 [2014]

I’ve done some searching but don’t seem to be able to find a product that is able to interact and control ST (not as a secondary remote, but as a primary). Does a product like this exist? Or is my best option to mount a zwave remote on the wall if I want it to function as a light switch/control for other ST connected things?
