Hello
You could maybe leave the bamboo in big pots and submerge them in the soil to keep it under control

?
I'd go with pelmetman's suggestions of runners and french beans.
You could you do some hanging baskets of cherry tomatoes & strawberries if you have something to hang them on? THey're always nice. I love Tumbling Toms.
What about a standard cordon (?) type Fruit tree? My mum & dad have an apple and it's less than 15 cm at it's widest point in full fruit so wouldn't block too much light
