Thank you.

Econ 2F03 has not existed for years; 2I03 is apparently a really fun and interesting course. Other than that, all those above courses are easy because they're second year economics. Personally, I'd suggest 2D03 because it has to do with heterodox economics (going by what Khan puts in his courseware), and 2I03 because it has to do with investment. But that's if you want to learn things, not just take bird courses.
