Companions for vined spinach and which ones aren't.

Greetings! Just wanna ask if there are any other plants besides beans and peas would compliment the vined spinach such as Caucasian Mountain spinach and others. In my food gardens, I also grow corn, beans and sunflowers. If they're still around, will the vined spinach co-exist with corn and surrounding stuff right now?
Looking to add tasting greens in my four or five sister gardens next year if the time is right. And which ones are bad near my vined spinach? Want my plants become allies to other plants in my gardens so they can thrive and create richness to the soil and welcome other sources of life to my gardens year after year. Please reach me in the comments to share some stuff with me if you need me. Sweet dreams!
