The two main things I consider with this question are

a) ANH is the best point of introduction to the setting. It does the best job of easing you into its world.

b) Jumping around too much in the timeline would be confusing to young viewers.

That’s why I’d go with the compromise of watching the OT first, then watching the rest of the films (and shows, too, if you want) in chronological order. If we were just talking about the episode films, that would make things even simpler, since that would just be Release Order. But the existence of the spinoff movies and shows requires that I find a place for them, and the best place I can think of is between RotS and TFA, treating them as appendices to the main story.

Shows like The Acolyte will complicate this, since they take place before TPM.
