Ditto on coons. They are incredibly strong and can rip chicken wire
Thompsen water seal is not a great product, even on dry plain wood. It will not work at all on OSB board because it won't soak in due to the binders used.
Paint is definitely the way to go...and yes it would be easier to paint the interior now if you want it painted for ease of cleaning and increased light if you use white.
Roost looks good, get the feeder and waterer out from under as it will get covered in poop....or put a board 6-8" under that roost to catch the poop.
Ventilation...where are you located? 1 sqft of ventilation per large fowl bird is recommended. Ameraucana is a large fowl. I would add another opening over the door as previously mentioned. Windows and vents should be open all the time, even at night, thus the HC. Ventilation is very important as birds are very sensitive to respiratory issues (ammonia laden air) and humidity causes frostbite if you are in a colder area, especially in a crowded coop.
4sqft per LF bird in coop and 10sqft in run is the minimum (IMO) recommended space requirement. You might be successful free ranging but if predation or extreme weather require confinement in coop, problems could arise due to crowding.
