What is this weird noise when opening/closing doors?

All seems pretty normal to me. Newer vehicles start priming systems anticipating the vehicle is going to be started and there's no ill effect if the vehicle does not get started. If you want to hear it make a bunch more racket you should shut the vehicle off and stay sitting in it for a few minutes and it will make all kinds of crazy sounds. All totally normal

ya it takes a couple minutes for everything to power down and go to sleep mode and it does it different all the time if you do it in the dark you can see the screen or other lights still on even minutes later and then the factory alarm kicks on and you get a blinking red light from the sun sensor, that might depend on your year model and options though.

Thanks all for the replies. Now I'm calm

Mine whirs and clicks whenever I am approaching with the key, getting ready to go, illuminating gauges, illuminating GMC out back to kick-open the rear gate, and who knows what else. I find it kinda cool, kinda. I believe you can control some of that in the computer. I've made some changes, like lock on its own as the wife likes to leave our cars wide open all the time.
