I currently work per diem, 12-hr shifts, and I work either days or nights, depending on my employer's needs. I rarely have a week that I don't work day and night shifts. There are benefits to day shift, i.e. it doesn't mess up your body's internal clock, and you don't lose days to having to sleep either in preparation for or after a night shift. Of course, night shift has its benefits, too, i.e. it is often quieter, way less non-nursing staff running in and out and making everything much busier, usually less meds to pass, blood sugars to check, etc. But it does impact your body clock and your regular life. Unless your family and all your friends are night shift workers, you're going to want to get back to a normal schedule on your off days. If you can work either all day shifts or all night shifts, that's what I'd recommend. If you do opt for night shifts, I'd try to get them all in a row, if you're doing 12-hr shifts. That way you don't have to try to flip back and forth multiple times in a week. Good luck to you!
