I'd say you're about dead on in my opinion at this point in the game.
From personal experience, I feel that the superman match-up is slightly in supermans favor (4-6). You can argue that parry negates his f23 breath pressure and the majority of his mix-ups, but all it really does is give good superman players additional mix up options. Parry is ridiculously punishable and if you're facing a good superman that knows that they can bait it out, you get some near 50% optimized combos thrown your way. Plus, as you said, the zoning game is clearly in supermans favor.
Also, I think the neutral jump only works if the superman player does the f23 too late, it will catch back-dash and neutral jump if they do it correctly. Feel free to correct me if I am wrong but I have definitely been caught n.jumping by good superman pressure.
