Hey Jon, peeks crossing - is that near mt Barney? ClissAT is all over it. Position the beds in full sun and you’ll be fine. Use the natural shade created by the plants to protect the specific crops that like part shade while the others enjoy the full sun!
Congratulations on finding the group! Spinach is a great first goal! There’s plenty of variety to cover all seasons so you should be able to harvest all year! I’d recommend Brazilian spinach, warrigal greens and Egyptian spinach for hardy perennials.
I had a problem with cutworms a few years ago. Was horrible coming outside to check on the garden and finding young plants dying. I’ve heard that broken baked egg shells around the base of each plant are meant to work but I’ve never tried it.
