I can understand wanting thermal expansion properties to be the same for construction of long-term, permanent structures like vehicles. But does this apply for FRC robot construction? In other words - why wouldn't I always use, say, steel rivets, for strength?

I would argue that aluminum rivets will work just as well as steel ones for most applications in FRC. We avoid steel rivets because it is difficult to drill them out. Any time we would have to use steel, we just switch to a screw.
