If I can leave it, where is the best place to make the final cut? Perhaps
just beyond the final group of leaves?

Cut only the dead wood off. My experience with red maple is that they often have spotted, random die-off as that.

However, if that limb, more so than other limbs, has a history of having parts dying off, then it might be best to cut off that whole limb. With the tree being that old, if that limb has repeated die-offs, then it may be a venue for disease, bugs, etc. to the rest of an aged tree. Seems the tree is pretty healthy, otherwise.
