electrical set-up for future garbage disposal

Everyone here has been so incredibly helpful, so thanks! Okay, one last question.

What is the best electrical set-up for a future owner to have the flexibility to install a garbage disposal? Put a receptacle in the back of the sink cabinet and run cable from it up to a switch in the backsplash? Just worry about running cable to a covered j-box in the back of the cabinet with the wires capped off? Something else? Don't worry about it at all?Would a disposal need to be on a dedicated circuit or could it be shared with the dishwasher?

I would probably just go ahead and install the receptacle in the back of the sink cabinet and a switch above the backsplash. A switch is less than a dollar, so why bother with capping it off and a blank cover plate?

The disposal can share a circuit with the dishwasher so long as both are typical "residential-grade" appliances. A 20A circuit with #12 wire would be preferred, but a 15A with #14 would be adequate.
