So, when theory crafting a champion which I plan to eventually take Celestial Form, I came across a couple questions. My first question is: how do Powerful Leap and Cloud Jump interact with each other? Do you add 5 feet after tripling (which would be rather lame), or do you triple after adding 5 feet?
My second question is: is there any reason at all take the various jumping-related feats (Quick Jump, Powerful Leap, Wall Jump, & Cloud Jump) if you gain access to flight (such as Celestial Form)?

Powerful Leap affects the Leap action, while Cloud Jump affects the Long Jump and the High Jump actions, so they don't really add to one another. If you're Long Jumping, you Stride and then Leap. If you have moved at least ten feet in your stride (or you have Quick Jump) and you are successful at your Athletics check, you jump however far you wanted AS LONG AS it's not farther than your Speed. With Cloud Jump, the difficulty gets slashed to a third of what it would be, and you can spend extra actions to add your Speed to the maximum possible distance.
Consider a character that has Quick Jump and Cloud Jump and a Speed of 25. They can spend all three actions to jump across an up to 75 feet wide chasm by being successful in a DC 25 Athletics check. Since they're at least 15th level and Legendary at Athletics, if they have a positive modifier to STR they can only fail on a roll of 1. If they do fail or critfail, they only move Leap distance, which in this case would be 10 feet, or 15 with Powerful Leap.
If they are trying for height, they can High Jump with the Long Jump formula, so a single action and a DC 30 check should enable them to jump 5 feet forward and 25 feet up. If they spent two actions, they can reach 30 feet up, or farther with a higher DC, up to 50 feet at DC 50. A third action would enable them to reach a height of 75 feet with a DC of 75, but that's a little beyond the scope of a 20th level character. If they fail the check, they leap 3 feet up, or 5 with Powerful Leap.
Having Wall Jump and being next to a wall would allow them to break that DC 75 Athletics check into three DC 30 checks; each success raises them by 25 feet and each failure by 3 feet, or 5 with Powerful Jump.
So, in my opinion, after you pick Cloud Jump, Powerful Leap is kind of not worth it.
