Pretty much all of the rides as long as he feels up to it. We went in 2000 and my nephew had a broken ankle. He was not really allowed any weight on it, so we had a wheelchair for him and the cm's put him (all 10 of us!) up to the front of the line for every ride. They were really great with him.
Things have changed since the late 1990s, early 2000.
You will generally be waiting in the same lines with everyone els because most of the lines are wheelchair/
ECV accessible (these are called Mainstream Lines). AK and the Studio were built with mostly Mainstream Lines and attractions at MK and Epcot have been changed to Mainstream of possible when they were renovated. There are still a few that have a wheelchair entrance because they were not able to make it accessible, but that's an exception rather than the rule.
Other things to think about......
If he needs his leg to be elevated, he might be better off with a wheelchair because you can rent wheelchairs from one of the off-site rental places with elevated footrests.
If he doesn't need his leg elevated, an ECV would be a better choice because there is a platform for the feet, which would give him a little more protection for his foot and also allow him to change positions of his legs somewhat. If you rent from one of the off-site places, you can also get a crutch holder so he can bring the crutches along with on the back of the ECV. There is information about renting
ECVs and wheelchairs on the disABILITIES FAQs thread near the top of the disABILITIES Board.
Also, many rides do involve a step down into the ride car and he may need to avoid some of those. It may make a difference to him which side the ride car is boarded on because it may be difficult for him to get out if his broken leg is on the exit side.
