There are so many variations of style for POV that what works for some, doesn't for others. Big Help, I know LOL. The main thing I have found is that the overlying POV is that of the author's narrator, the overriding "voice" and "opinions" of the story. That is essentially, the POV whether it is an all-seeing, all-knowing type or a specific "observing" individual. If it's an all-seeing POV then you can probe into the minds of all the characters, describe what they do when alone, etc., obviously not so with a specific individual who only knows, sees, etc when this individual is present (but, of course, may speculate about when they're not present).

A consistent POV from a specific narrator (non all-seeing) provides a good medium for dynamic tension and "surprises." Good storytellers usually give the reader the sense that it's someone who is able to put them in the picture, and who knows the outcome (hence a lot of good stories are like hearing them "as history." They did this, they did that, they felt/thought this or that (doesn't have to be told in the past tense however). The POV of this individual storyteller also can provide insights (or hindsights) into the meaning of the story as it develops. Dunno if any of this is helpful. I've been a writer for well over 40 years and am still always learning and re-learning the craft of making words do what I need them to. *S*
