If you want privacy, bamboo is great, and the leaves make great compost, the timber gives you materials, and you have food from the shoots if you pick an edible kind.
Many edible kinds are small as well, I have one kind can be eaten raw, it is spindly and bush and maxes out at about 20 feet, very slow growing. "Bong Waan Sai Nampeung"
Another kind maxes out about 30 feet, nice looking timber, relatively fast growing. "Gim Ju"
Some other kinds get to 100 feet and provide huge edible shoots, but so far these rot out at my house during floods, likely for the better these are so huge.
I think most people go wrong when trying to maintain bamboo when they cut it to a stump, proper maintenance of bamboo is cutting below the dirt, cutting the entire shoot off, if you have edible bamboo you will be doing this anyways, so maintenance and food come hand in hand.
