PTFE is the correct choice in my estimation when replacing factory steel on those and the engine oil cooler lines. The temperature rating and pressure rating make them the best option from my research.
MRB9265 from Kartek.
My transmission cooler is bigger than the original. It is from our old '94 Suburban. About the same size as the oil cooler. It swapped in without issue. Swapped bracket between trucks.

Is that a 2131702 o2 sensor...

White steel on the ceiling is finished as soon as it's up. It's light to lift up into position and two people can hang it easily. Drywall lift and/or a wooden "T" make it a cake walk.
Sheet rock would be a mistake under those conditions.
Panels look promising. Probably better than steel interior panels due to less chance for condensation.
My ceiling and dad's ceiling are white steel. Walls are painted OSB
