Low Maintenance Garden Ideas for Northern AZ

I would appreciate any ideas, tips or recommendations for a low maintenance garden.

I recently bought a place in Northern AZ that already has some raised gardens beds in place within a deer proof fence, there is also an automatic watering system set up. I travel a lot and have an unpredictable schedule so I was hoping to start a garden that would require very minimal upkeep and wouldn't be high maintenance. Anything from herbs, cut flowers, fruits and vegetables. The garden beds are in full sun but I could possibly build some partial shade structures if needed.

I know its a little early to be planting anything now but I just wanted to be prepared for when the weather starts to warm up.

Google varies on deciding what zone I am in so it ranges between 6b, 7a, and 7b. Elevation is 5,100 ft

Thanks in advance for any notes.
