Totally! Jennifer, it would help if you gave us some ideas about your general climate and how hot and sunny your garden is.
You'll get many differing opinions because each climate and gardener are unique.
I suspect that with your listed zone being 8a, you're right about your observations. Where I live, they recommend north/south rows for the airflow. I tried east/west when I first got here as my garden was on a slope, but everyone pushed for north/south, and now I've ended up with more of a block pattern which proves even more that there isn't one right way - just lots of ways to try.

I live where there is lots of sun so I plant by height. Again, I don't know why, I put the tallest plants on the south side of the bed. The reason might be so the tall plants will shade the shorter plants in the afternoon.
The first year we moved here I did my rows north to south, then on the south end I turned and went west to east. What I plant east to west worked. Maybe that is why?
