Notes and bibliography uses footnotes with a bibliography, and is usual in history and the arts. Author-date uses in-text brackets like APA and is usual in the sciences. Choosing the wrong one is a bigger error than any punctuation mistake. This generator produces the bibliography entry.
The same source is punctuated differently in a note and in the bibliography: the note uses commas and does not invert the author's name, the bibliography uses full stops and inverts the first author. Copying one into the other is the commonest Chicago mistake.
In the bibliography, the first author is written family name first so the list can be alphabetised. Every author after that is written normally.
Whichever your department asks for. History and the arts usually expect notes and bibliography; the sciences usually expect author-date.
For books, yes. Chicago kept the place of publication where APA 7 dropped it.
A student-facing adaptation of Chicago, maintained separately. The patterns are close but not identical, so follow whichever your course names.
