Answer:
The answer to this question really does depend on where you live and what you mean by large. Most commercial tree crops are grown on trees that have been grafted on to dwarfing root stocks so that the trees do not grow to tall and the crops can be accessed more easily, and modern pruning methods also tend the same way. These answers are based on knowledge of temperate and Mediterranean Europe and as such could be applied to parts of North America also. If you want trees of 100ft or more then sweet chestnuts walnuts and pecans. In colder areas in Europe Walnuts work well. Sweet chestnuts need to be slightly warmer to get a really big crop. If 30 - 40 feet is tall enough then there is a huge range of top fruit, apples pears and plums in the temperate regions and peaches apricots and oranges further south, If it is calories per unit area that you are looking for then olive trees can be a good bet. Trees such as apples, pears, peaches, olives etc. have a large number of cultivars and different varieties will grow better in different locations. Something else to bear in mind is that most fruit trees are not self fertile, if you are only planning to plant one tree, this will severely limit your choice. If you have space for two trees pick varieties that will give a good range of product but will fertilise each other efficiently for example a cooking and an eating apple or an early with a late pear tree
