If it's a philosophical topic, try starting with the Stanford Encyclopedia of Philosophy. If it's a scholarly topic that lends itself to testable predictions, use Google Scholar to search for highly cited and/or recent review articles, and read on sci-hub if the article isn't already open access. If it's highly controversial and not particularly testable, then I recommend A) prepare yourself to consume a lot of primary sources and make difficult judgments on your own and B) prepare yourself to live with the problem not feeling satisfactorily resolved even if you do A for a long time.
