Anything by Terry Practchett, although perhaps it's not as "canonical" as other suggestions, as he tends to deal with these specific topics frequently in a fairly incisive deconstruction, framed humorously. Small Gods, Pyramids and Thief of Time probably are most relevant. Any of the Death books relate to many of those though, also most of the Witches books, in various ways, but slightly less directly than those. The Watch books, and any of the Moist books cover some aspects of the listed ones. I realise this is most of them but, problematising modern society by satire (and actual satire, rather than the cheap pseudo "satire" used by e.g. South Park, anything by Seth McFarlane, and so on use) and reference.
In the more canonical literary sphere, Fear and Trembling, by Amelie Nothomb, offers an alternative perspective of Japanese society viewed from the lens of a westerner working in a business corporation there. It's quite funny at times, and is useful in illustrating that what is often considered "universal" from the perspective of western social sciences is in fact specific to those cultures. Natsuo Kirino's writings, while quite gritty and often very dark, also offer great insight into the nature of Japanese society, which is again useful as above. L'Étranger by Camus touches on all of those topics, and introduces some concepts of his existentialist philosophy (which is specifically somewhat different from Sarte's).
More academically, you can't really go wrong with Jared Diamond, who discusses various concepts most of which relate to human society and evolution, across his books. Guns, Germs, and Steel, and Collapse, might be particularly relevant. The Black Swan introduces a common fallacy and discusses the implications of it. J.S. Mill's and Bertrand Russell's texts are often used as introductory forays into Philosophy. The Innocent Anthropologist I often see recommended as introductory reading for social sciences (not just anthropology) as it again points out the differences in western and other societies and how the assumption that the former is somehow more fundamental is problematised, I hear, in a fairly entertaining and enjoyable way. Dworkin is the usual reference for jurisprudence and might be interesting in terms of the notion of crime and justice as a result, although I have no idea how accessible his work is (I suspect not very). There's also Dawkins, although I'd suggest taking anything written by him with several large grains of salt.
Plus there's the usual suspects, the benefit you'll gain from which is debatable; Nicomachean Ethics, The Prince, The Republic, Meditations (Descartes or Aurelius, they're separate but have the same dumb title), etc, etc...
I wouldn't recommend anything beyond the first three sentences of the third paragraph in honesty but those other things tend to come up time and again so you may as well know what they are and hopefully avoid them until a little later.
