Being XO doesn't mean you're next in line for the Captain's chair of your current assignment. Sisko is an experienced commander and war hero. In a real life military that would make him a top choice for the fleet's flagship. Kira may be a longer shot. Looking at Kira Lit history on Memory Beta, I see she is also an experienced commander and held the rank of Captain in Starfleet. So again, a real life military would see her as a viable commander for the Enterprise.
But Starfleet is neither a real life military nor, although having aspects that are very similar to a military is it actually a military force.
So is there an "in universe" reason a person like Sisko shouldn't be the CO of the Enterprise? Because looking at his CV, I'd think any organization, military or civilian, real or imaginary would have him on the short list for a leadership position.
Starfleet is military. No matter what Roddenberry in his later years or anyone else might say, When the UFP goes to war Starfleet is who fights it.
