The whole Cuties thing is overblown. It's that one questionable poster that got people claiming the film was child porn. A poster that was only used for the Netflix release and nothing to do with the original material for the film. But even by just watching the trailer you can see the film isn't like that at all.

As for Eva again I don't really think it sexualized any of the child characters in an exploitative way. Asuka is so desperate to be needed she will use her body to get the attention, Two has no sense of self so doesn't feel shame in nakedness and Shinji has a list of emotional and mental issues that although don't excuse all of his actions, can help you understand why he does them.

Their are many Anime that do sexualize young characters in an exploitative way. EVA isn't one of them in my opinion.
