I like the WISC-V better, too. Combining VS and FR under PR has always bothered me. The CPI has been available for quite a while, even on the WISC-IV, just not in the standard scoring software. (Needed a separately-purchased interpretive handbook for it.) It does make the value of the GAI much more noticeable, as you can now see the contrast between GAI and CPI more vividly.
Your overall cognitive results are good, with strengths just where I like to see them. The only really significant relative weakness is in processing speed, which makes sense when combined with the DKEFS results. Academically, it is not surprising that some inconsistencies will begin to show up with a child diagnosed with ADHD. Multi-step math operations, inferential reading comprehension, and extended writing are some of the places that are particularly vulnerable to the deficits in sustained attention and organization.
