Well, got all the lights working. Still don't know what the switch is for... will use the tester to see if I can get that figured out.
The light issue was really simple... turns out the switch for lights by the microwave is under the cabinet. And the other set of lights are controlled by a smaller red switch. But very obvious and labeled. Not so proud of this moment.
Thanks for the input. I learned about the tester and about the switch under the cabinet. Which should not have been a question since so many other lights are controlled by switches in similar places.
My apologies for not spending more time before posting.
