Live Jazz is the first one that comes to mind.
As for Kouros and friends, let's be honest, it's not safe to suggest Kouros as a fresh, clean scent. Of it's friends, I would have to say that one that got mentioned, Kouros Fraicheur, isn't particularly clean. It has some freshness going on, but it is way too dirty to be clean. Some of the Kouros summer versions are more clean, but by far the cleanest Kouros variation is Kouros Cologne Sport.
As for Opium, uh, just not clean at all. It is a heavy fragrance filled with vanilla and spices.
M7 Fresh is fresh, but not particularly clean. As long as you don't need your scent to be squeaky clean though, this one could do the trick.
In summary, I'd say your best options are definately Live Jazz, Kouros Cologne Sport, and M7 Fresh. All 3 are good scents, but in my experience take time to grow on one, especially the LJ and M7F. The longevity of KCS and M7F are questionable on me. I think that Live Jazz is the best of the three.
