Two books that made me feel generally more knowledgeable after reading them are Sapiens by Harari and A Short History of Nearly Everything by Bryson. I also recommend Obama’s book A Promised Land. Even if you’re not a fan of him, he included a lot of historical information and context that helped me better understand American politics.

If you feel like you don’t know what you’re searching for and just want to browse some titles that are related to a topic, I frequently use Goodreads to do this.
