Question on orientation when planting row beds between orchards

I am in the process of designing a 72 x 72 garden/orchard that will consist of 4 foot wide row beds between rows of orchard trees (avocado, pluot, pomegranate and fig). The trees size will vary but I’m looking at semi-dwarf. My question is… should I lay the trees and bed rows out north to south, or east to west. I remember reading in the past that there are different benefits for each but am looking for the layout that both allows for me to make the most of the space while also creating row beds that will potentially get enough sun to grow full sun crops. Latitude is 34.448050 in Ojai CA.
