This is kind of a small detail, but I hope Humanity in the Picard Series is portrayed a little bit differently than in Discovery. With its 23rd Century Setting, it makes sense for the crew of Discovery to not act like the crew of the Enterprise-D. But, at the turn of the 25th Century, they probably actually still have some of that stubborn "we're evolved!" attitude. Even after the Borg and Dominion. It would make them look hypocritical but at least that could be pointed out by other races as a flaw that Humans of this time have.
I view the Federation of the TNG Era as something that became a little too comfortable with itself. Which explains both the change in mentality and why the technological differences between the 23rd and 24th Centuries never seemed as pronounced as they probably should've been. They're content, they slowed down. Then they were caught unprepared, as both TNG ("Q Who?") and DS9 ("The Jem'Hadar") showed.
