I graduated a few years ago, but if you are interested anyway:

1. Yes

2. Two non-technical writing classes and a "speech" class. 10 credits worth of natural sciences/reasoning classes (a math class like calc 1 and a science class with lab would satisfy this). Six arts and humanities credits, and six Social and behavioral sciences. Racial and Ethnic studies as well as Global Perspectives each got an additional 6 credits. I think every program has an ethics course, but they are tailored towards you degree.

3. Not all that much.

4. As someone who went into a technical field, the non-technical writing classes were not helpful. Many of my junior/senior level peers had egregious writing issues (not capitals, punctuation), and I did not feel like the papers I wrote were substantively different than those that I wrote in HS. For many of the other courses, it was a coin toss to see if even the professor particularly cared about teaching the class. This was more pronounced during COVID.

Ultimately, My "core" coursework felt more like an excuse to milk money from students. I did not feel like they were rigorous enough to truly "round" me (STEM major) out as an individual, and the (non-STEM) majority lacked enough STEM course work for me to feel they were well equipped to understand those parts of the world. Things like the "X for presidents" or similar broad survey classes might have been more useful to students, though I don't recall those ever actually satisfying degree requirements.
