OK, I have more time now to offer more detail for the specific questions I didn't directly answer last night.
In a hot climate, the best coops are made of as much wire as possible. 1/2" hardware cloth, possibly reinforced with a layer of sturdy 2x4 wire if you've got a lot of larger predators, especially feral dogs.
An Open Air coop is, essentially, a roofed wire box with a 3-sided shelter on the windward end. Maximum ventilation, as shown in my hot climate article linked above.
That's entirely a matter of personal preference. If you go with the Open Air design, combining coop and run into one unit, a dirt floor with bedding over it and a wire anti-dig skirt to keep predators out, will be the easiest to construct and maintain.
Another personal preference thing. Shingles over plywood are a lot of labor. Once upon a time, it was cheaper than metal but with the current inflation of wood prices it may or may not be.
We chose metal over purlins for ease of installation.
The various forms of plastic/fiberglass/etc. have varying reputations. The critical thing in a hot climate is to absolutely NOT use a clear or translucent roof because it would turn the coop into an oven.
I actively advise against Ondura. It's heavy and does not stand up well to southern weather. There was an Ondura-roofed structure on this property when we moved in, but the roof was utterly shot despite being only about 5 years old.
I used old screen doors -- reinforced with a layer of hardware cloth.
Automatic doors are reputed to be a great convenience. I will soon find out because I have one that I haven't installed yet.
That depends on your management style. I use deep bedding/deep litter so there's no point to poop boards. For others, poop boards are a great convenience.
It's very handy to be able to brood in your coop. It starts integration on day 1 and smooths out the transition.
I don't brood in my coop right now, but I do brood outdoors and I love it. I have no worries about my chicks making the transition because they acclimate all along.
That's another personal preference. How big your coop is also matters.
With the Little Monitor Coop I HAD TO keep feed and water in the run: https://www.backyardchickens.com/articles/an-outdoor-shelter-for-the-feeder-and-waterer.76487/
With Neuchickenstein I still use that shelter, but it's convenient to have feeders inside too.
That's another personal preference thing. How fine a finish do you want? How much does appearance matter?
Barn paint is designed to go onto unprimed, rough wood without pre-sanding.
I would LOVE to have a coop camera, but haven't been able to justify it on my budget. It's a cool thing to have if you have the money and *can* be important beyond just the entertainment value if you're suffering predator breaches or, worst case, human-caused security breaches.
Coop
- What is the best material to create a coop?
In a hot climate, the best coops are made of as much wire as possible. 1/2" hardware cloth, possibly reinforced with a layer of sturdy 2x4 wire if you've got a lot of larger predators, especially feral dogs.
An Open Air coop is, essentially, a roofed wire box with a 3-sided shelter on the windward end. Maximum ventilation, as shown in my hot climate article linked above.
- Should the floor of a coop be the ground?
That's entirely a matter of personal preference. If you go with the Open Air design, combining coop and run into one unit, a dirt floor with bedding over it and a wire anti-dig skirt to keep predators out, will be the easiest to construct and maintain.
- What roofing material should I use?
Another personal preference thing. Shingles over plywood are a lot of labor. Once upon a time, it was cheaper than metal but with the current inflation of wood prices it may or may not be.

- Best door material? Should I have an automatic door to open for the chickens?
I used old screen doors -- reinforced with a layer of hardware cloth.
Automatic doors are reputed to be a great convenience. I will soon find out because I have one that I haven't installed yet.

- Are poop boards a good idea?
That depends on your management style. I use deep bedding/deep litter so there's no point to poop boards. For others, poop boards are a great convenience.

- Should I create a brooding area for new chicks?
It's very handy to be able to brood in your coop. It starts integration on day 1 and smooths out the transition.
I don't brood in my coop right now, but I do brood outdoors and I love it. I have no worries about my chicks making the transition because they acclimate all along.
- Best feeding and watering arrangements?
That's another personal preference. How big your coop is also matters.

- Should I sand materials?
That's another personal preference thing. How fine a finish do you want? How much does appearance matter?

- Should I include cameras?
I would LOVE to have a coop camera, but haven't been able to justify it on my budget. It's a cool thing to have if you have the money and *can* be important beyond just the entertainment value if you're suffering predator breaches or, worst case, human-caused security breaches.
