As a sidenote, 4chan has moderators, they are just called "cleaners". And 4chan is far from the wild west people imagine it to be, with the exception of some general cesspool boards like /b/, /v/, /pol/, etc. that cater to the lowest common denominator and are super general in terms of topics discussed (which naturally attracts a ton of people). More niche boards (most of which happen to be categorized as SFW) have some pretty good material, tend to stay on-topic, and are indeed suited well for a civil discussion. My personal favorites would be /o/ (anything car/vehicle related), /toy/ (for stuff like assembling/painting/working on models), /lit/ (for literature), /diy/ (self-explanatory), and /sci/ (science&math). Yes, it isn't super concentrated serious material with no fun allowed, e.g., there are occasional threads where people do things like build a motorized bathtub and then proceed arguing about feasibility of making it street legal. But the quality of discussion there isn't that bad at all, and the moderators are pretty strict about banning people and deleting threads for either being unrelated to the theme of the board or for NSFW stuff on SFW boards.
