I like the video - definitely helps focus on the key areas for help.
With regard to lighting - it is recommended that lighting face away from the house. I see you have one facing the house (opposite the sun deck). Can that be changed? Since you have lighted bubblers, do you need another light on the sundeck?
Can you put 2 on that side facing away from house and 1 on the deep end as you have it? If you have the room, one under the sundeck may be workable and better than on that short side in shallow end.
With regard to returns. First, I would plumb the 2 skimmers as separate independent lines back to the equipment pad. This way you would have 3 suction lines - 2 skimmers and the main drain.
I would have 4 returns - add one in shallow end between the skimmer and the sundeck facing to the deep end. Then on that top right corner of the deep end have another return facing to the shallow end. That would provide good circulation around the pool. I would have minimum 3 returns if you cannot have the 4th.
You mention 1 pump but have 3 deck jets, 2 bubbles and a future slide plus the returns. That is a lot for 1 pump especially the slide. Have you calculated the needed flowrate for each and determined if the pump and pipes can meet that? Each deck jet and bubbler should have stated flow rates. I really think if you plan to add a slide, you will need a separate suction line and pump for that. Can you at least add the suction line and return line for the slide now before you get too far into construction?
Also, I would not use those plastic blue on/off valves to control the deck jets and bubblers. They cannot be serviced. Use a 2 way valve that can be serviced and you be much better off in the long run.
I am sure others will chime in but that is my initial thoughts.
