Also, why couldn't they pick Sarada be the "sun" since Orochimaru was more interested in Sasuke than Naruto. Sasuke opened Orochimaru's eyes to other possibilities. Considering his plans with Mitsuki, and his "moon that illuminates the dark", it seems Orochimaru wants him to emulate Sasuke. And hence, Boruto should fill the role that Naruto once did for Sasuke.

Although, Mitsuki's mission is to generally observe Konoha and learn to be a complete human. He mentions he trusts Sarada, so i would imagine he also observed what Sarada did.
