Case management may not be for me?

I’m a fairly new, inexperienced nurse with only 1 year of experience. Though I also took a year away from nursing for a year too to focus on my mental health and get away from the bedside. Now, I’m ready to get back into nursing but I would prefer a day shift position that is not at the bedside. So far, I received 3 offers for the pediatric OR, school-nursing, and a case management position. All my interviews seem to like me because I’m a good talker, and I try really hard to sell myself. I turned down the school nurse position to focus on my other two offers.

I think I want to be an OR nurse but I’m not sure how the on-call requirements would affect my work-life balance. That is most important to me. 
 

For my case management position they said that I will take care of 1300 patients. My team would consist of a provider, medical assistant, and a administrative support. My duties would be a lot of administrative tasks and coordinating the care of patients with my team. The position is 8am - 5pm mon-fri with 1 hour lunch break. I would also have 3.5 weeks of vacation for year of service then it will continue to increase up to 6.5 weeks. The only thing that really is doubting whether I like this or not, is that it seems like it would be very stressful to care for that many patients. And they ask whether I would be comfortable with straight catheterizing patients and do some wound care when needed like once or twice a month. Though this seems more like bedside work which I was not thrilled to know. 
 

So does the duties of this CM position raise any red flags to anyone? I’m not sure if I should actually accept the offer or not.
