Welcome to ILGM @TheCrozh!
I haven’t done any outdoor growing yet, but your plan sounds solid, timing-wise. I’d go for the largest containers your budget will allow for the medium to fill them. In 5 gallon pots, in mid summer, mid flower, they’ll be drinking the water about as fast as you can pour it in. That’s exaggerating, but not by much. They should handle the heat okay as long as they have the water and root mass to deal with it. Make sure you’re giving them Silica in some form, to help build strong cell walls, and for protection against insects AND the elements. It’s possible to grow a healthy enough plant that it is its own pest control to some extent.
I’ve also never grown autos. @Big123 grows monsters outdoors and comes to mind first. Where he is doesn’t get as hot, I don’t think, but I’m sure he can add some advice. The timing of your transplanting is something to consider. If autos are stressed at the wrong time, it can induce flowering before they’re very big, and yield can be hurt quite a bit. You might want to implement some shade cloth to harden them off more gradually between shade and full sun.
As for drying, I’d try to find a closet or somewhere else that doesn’t get much traffic, temp fluctuations, etc., and setup a small fan to blow indirectly, so there is airflow around them, and they’re in the dark as much as possible. You can slow drying by cutting the whole plant, and leaving as many leaves as possible. The extra moisture in the plant material will help slow the drying, and the leaves will sort of fall over and protect the volatiles to some extent. If it’s too dry (below 55% or so, it’ll likely dry too fast), you can add a small humidifier to fine tune the drying space.
If you prefer to wet trim, I’ve seen others trim them down to individual colas, then dry those in a paper bag or cardboard box to slow things down, then do a final ‘manicure’ after drying. I’ve used a box myself with decent results. I just poked about a half inch hole in opposite corners, one of top one on bottom, to get a little more airflow through there. Then I stretched several strips of string across to hang colas from, and even mounted a hygrometer in it that could be read from the outside. Worked well to dry slowly even when it was 10-15% relative humidity and 110°F outside. The paper/cardboard helps draw moisture out of the plant material, while keeping some of that humidity within the container to keep it more humid than the surrounding area.
Sorry, brevity is not my strong suit, and I’m well medicated. Welcome, and best of luck! The only dumb question is the one you don’t ask. There are no high horses or bullies around here, for the most part. We’re all just trying to help each other grow the dopest dope!

Since I began growing (around April 2020), I have been in school reading and learning on this great forum!
SOrry, I too am medicated and not brief, and I am procrastinating. But this is still pertinent, as I plan to trim this AK today or tomorrow (has been in the dark alone for a day now).
