For what it's worth, I agree with you. I consider myself multisemilingal- English is my primary language, but I have up-goer 5 levels of proficiency in half a dozen other languages. I enjoy it, but I do not feel like it has been a net improvement in terms of cognitive function. If anything, more mental housekeeping is required when I sit down to write in any language, including English. I think many people, even multilingual ones, fail to truly consider what they mean by 'multilingual'. Words and grammar are only the bare surface of what you need to learn- what actually happens is that you grow a different model of mindset and culture, one where the words of the new language have meaning. This only happens over a lifetime of immersion and exposure to the prosaic realities of the language in question.
