I'm afraid it's difficult to give you a straight answer. I've been dealing with one case recently where the LA panel discounted all
curriculum-based evidence on the basis that it was irrelevant because their 11+ was a test of innate ability and nothing else! - One would have thought they would welcome something like CATs but they claimed not to understand an NVR score from an Ed. Psych! I doubt whether your panel will be as blinkered.
In so far as one can generalise, my usual advice is to provide as many different measurements of high ability as possible, and I would give CAT scores at least as much weight as a set of optional SATs results.
Wherever possible, evidence should be submitted in advance of the hearing as it helps the panel to have time to consider it.
Your DS's optional SATs results and CAT scores show that he is very bright. Percentiles in the mid-90s are exceptional. I assume that CAT maths = quantitative reasoning?
If I have just a slight reservation, it's that the NVR score is a little borderline, and appears to confirm the 11+ result. There is also said to be a link between NVR and Maths.
On balance, I think if I were in your shoes I would submit the evidence, and hope the panel focus more on the quantitative reasoning ......... but it has to be your decision.
