Clover cover crop

I’m about to plant 12 hazelnut bushes, 22 chestnut trees, and a few rows of mixed berries. Originally I was planning on applying bark mulch annually to suppress weeds, but I’m interested in opinions here on whether white Dutch clover would be a good cover crop to plant in the rows of the bushes and trees to keep the more unruly weeds down and help rejuvenate the soil. It seems like there are a fair number of up sides, but before I commit, I was hoping for some experienced advice from this group.

My only major concern is keeping the clover from spreading too much to the surrounding areas. I’m also curious if clover cover can take the place of mulch, or if mulch is still recommended around these plants to begin with.

I’m in zone 5b.
