If you work for a world wide freight operator you will fly both nights and days. Chances are if you are on the other side of the world from your home city and flying a night trip it is really a day trip for you!
Really, all flying is what you make of it. I have been a regional airline pilot, a major US airline pilot, a contract pilot in India and now a wide body cargo pilot. I am actually enjoying freight flying more than anything else I have ever done. With the lack of jobs for new pilots in the world today I don't see how you can be picky anyway.
