I did self adhesive led strips mounted to 1/4" aluminum angle stock. I screwed the aluminum stock to the face frame under the cabinets and oriented it so the led strips were facing the wall and one side of the angle stock was facing towards the countertop.
I used a dimmable 12vdc power supply and put it on a standard 120vac dimmer switch. The aluminum acts as a heat sink and when you look down at the glossy counter top, you can't see the leds. Worked pretty well.
If you haven't already, you may consider using a double gang box and getting a dimmer. They're UL listed so they can be inside the outlet box and they work great with Lutron (or other) 120 dimmers.
I've done a couple installs of under cabinet LED strip lighting and I've found these LEDs to be very nice for the price: https://www.amazon.com/gp/product/B00R5NUUAK/. I used a 40W magnetic transformer like this: https://www.amazon.com/gp/product/B007KWVFXC/. If using a dimmer switch, you need to use one compatible with magnetic transformers, like this one: https://www.amazon.com/gp/product/B0006UUI06. Electronic transformers are another cheaper option, but you'd want to look into the pros/cons.
