1. `collideWorldBounds` is for whether there’s a collision at all and `onWorldBounds` is for whether you want an event fired for it. Inside-or-outside isn’t really covered. You could use Rectangle.Contains() or maybe a special overlap collider.
2. See [Arcade.Group#defaults](https://photonstorm.github.io/phaser3-docs/Phaser.Physics.Arcade.Group.html#defaults__anchor).
