Indoor pool. DIY remodel for walls and ceilings. Am I crazy to use cedar fence pickets?

Hi! First-time post here. Looking for feedback from people more experienced than me.

We have an indoor pool that is very colorful and tropical flavored from previous owners. Interior walls are painted T1-11 on 2x4s with 6 mil vapor barrier with batt insulation and exterior Hardie board siding.
Ceiling is marine grade painted plywood.
We have some exhaust fans for ventilation, but plan to add two more in ceiling.

We are trying to aim for flagstone pool decking and a wood plank type look for the walls. See this AI image. And also trying to ball on a budget.

Keyword: budget. Hence no tongue and groove cedar planking (would be ~$12k)

With this in mind, I was thinking we have three options for wood planking.

1.) Either buy 75 sheets of plywood ($1.8k) and rip them into faux planks (SO MUCH TIME), or

2.) just buy cedar fence pickets ($2k) , or

3.) buy SPC vinyl flooring ($4k)

I'm thinking of doing the fence pickets and letting them dry out all summer to minimize bowing and cupping, then stain (marine grade) each side of them and nail to existing T1-11 interior walls and plywood ceiling. Will use a planer if needed, or quick sand the edges and front face.

Questions:
1.) Would you advise against this?
2.) If I go this route with the pickets, should I Tyvek wrap the interior T1-11 walls?
3.) Would you stain or epoxy the pickets?
4.) If this is a horrible idea, do you have any recommendations for a cost effective approach that gives the wood paneling look with mold and rot prevention a key priority?

I did a bathroom wall with pallets. It came out very nicely if I do say so myself. It also cost me nothing but some stain. Granted, it is a LOT smaller than what you are going for, but if you have a source of clean pallets then maybe it is an option. They need to be clean and not used to haul/store toxic things that can off gas. My brother in law works for a food manufacturing company, so I was able to get pallets used for shipping bulk food products so they were not soaked in machine oil or anything like that. They did need a quick sanding with 80 grit in some spots to remove surface dirt.
