The choice of POV has nothing to do with whom you think the main character should be. The POV determines what information you want the reader to have. If you want to do this in multiple scenes or chapters with each one from a different character's perspective, great. You can do it in any sort of first, or any sort of third; just pick one and stick with it. (N.K. Jemesin wrote a book in frame narrative alternating between third ominiscient and SECOND PERSON PRESENT TENSE. And it won like every award anyone could think of, if memory serves.)
I still write in old-school omniscient third, meaning there's an invisible narrator between the characters and the reader. The narrator is coloring the scenes and adding (or omitting) information all the time.
Because POV determines the reader's knowledge of the story, you need to know what your story is, what your theme is, and most of all, the point you want the book or story to make. When you have that, choosing POV is easy.
If you're pantsing, you either need to keep POV and character knowledge in your head at all times and choose your lens character, or be prepared to write every scene from every possible character's perspective until it clicks.
