If it were mine I would remove the limb in red. It would be benefcial to start tying those scaffold branches down as well. Cages tend to increase vertical growth tendencies.

Alternative would be to leave it and remove the one directly above it on the trunk. The way the tree is now, all the branches come out of the trunk at the same place, which can be problematic--a weak crotch. So putting a little weight at another point on the trunk instead might be beneficial.

I would leave it too but cut the top inner branch of the red one off. It's hard to tell the angles of the other scaffold branches, but I would cut one of those off too and then let another one grow out higher up for the reasons mentioned above.
