I’ll grant that some of the restrictions seem overprotective. That being said, a parent could easily check out one of those books for their child.
When people say "banned book" they mean that a certain level of government such as a school board or municipality has "banned" them from being in a public (often school) library.
But the headline "In [state I disagree with] they are banning books that have [ideas I agree with]" makes a lot more headlines and clicks.
Then people run with the phrase "banned books" to make things sound worse than they are.

USA is ultra conservative on the average in comparison to just any European state for example.
Are you serious? The UK and Germany are arresting people for social media posts. That is actual impingement of free speech.
Purely obscene material is also not protected by the 1st, but since the 1970s, the bar for that has been placed very, very high.
The closest I can think of offhand is that for about a year during the pandemic, Twitter suppressed gratuitous COVID misinformation posts, at the request of the government.
The evidence is that they don't serve it for school lunches.
Is that a weird argument? That's the same way people argue that books are "banned" in America.
