It seems obvious to me that at least some food crops were domesticated before the time Göbekli Tepe was built, at least 12,000 years ago. It seems very unlikely that hunter/gatherers could have supplied an adequate supply of food for the number of workers, and probably their families, that would be required to construct that temple complex.
Organisms evolve to thrive in available habitats or niches. To thrive in a human made field, a plant could develop "weedy" traits or traits that make it a desirable cultivar. I think any intentionality on the part of humans is just another environmental factor like climate or soil type.
