I'd say either Moral Issues or the Health and Society one - a course covering the entire philosophical sub-field of Ethics may be a bit unwieldy. (For example, you may spend an entire unit talking about environmental ethics or just-war theory, whereas the other two courses would be limited to health care issues)
Although, in my experience with philosophy and especially ethics, the papers are quite easy to write as long as you're familiar with which philosophers said what (sometimes philosophy boils down to name-dropping
)
