If these are correct:
- Tire with more contact patch take a shorter time to increase tire temp
- Tire with more contact patch take a shorter time to increase tire pressure
- Tire pressure increase automatically during hot weather, and decrease during very cold weather.
- Recommended cold tire pressure is 36F/42R. After riding for a while, tire pressure stays around 38F and 45R - this is the best pressure for grip.
Will this be true too? If the weather is hotter than usual, and tire shows slightly above recommended, but below “best grip pressure”, I don’t have to reduce it back to a lower recommended pressure?

Desired tire pressure can vary from rider to rider; based on specific tires, air temp, riding conditions, speeds, rider weight among other variables.
Guys that do track days will have a lot more experience than I do with it.
The 36/42 recommendation seems to be pretty standard across most sport bikes, likely as it limits manufacturer liability the most.
In general, the higher the pressure the more it will increase tire life and turn in quicker. The lower the pressure gives better grip (more contact patch) when cornering.
If you live in a flat area with limited curves, higher pressures will probably help lengthen the life of the center of the tire without sacrificing much.
Testing different pressures is probably the best way to figure out what suits you/your situation best.
I ride a lot of back country curvy roads at a spirited pace.
I started out using 32/36 (what I used on my previous bike).
However I didn’t like the turn in/steering feel and when quickly shifting side to side.
I went to 34/38 and seem to like the steering feel better, and I don’t think I’ll ever be riding fast enough on the street to outride the grip of my tires.
When my wife is riding with me I take the rear to 42 to compensate for the additional weight/load.
Dave Moss is probably one of the best experts on motorcycle suspensions (at least with an online presence).
A good basic overview from him on tire pressures, but he has plenty of other good videos.

Recommended tyre pressures are for maximum load.
Like everything it comes down to what works best for you and that means compromise.
Higher pressures, longer tyre life, less grip.
Lower pressures, shorter tyre life, more grip.
Like already mentioned, different pressures give different handling characteristics.
Then there's single, bi, tri compounds and the variations go on.
Read my second sentence again.

For me, the ideal pressure is 33F/36R cold, but I'm only 160# (sans gear), always ride solo (and unloaded), and since I like to ride the twisties aggressively (as far as lean angle, not rocketing from corner to corner), my bias is towards grip. At those pressures cold (they're obviously higher when riding), my bike feels rock stable in the corners, and handling is confidence-inspiring. But as mentioned several times, you need to play with pressures to see which ones are best for YOU. It's also dependent on which tires you have.
