I should emphasise though, that I am not technically minded at all and come to this from an ordinary car without DCC. And not a GTi!
Did you buy the right car for you?
The mk8 is full of tech, even though you don’t have to use much of it, similar to a smartphone you do need to develop a basic understanding of the UI. I’d imagine some features are infuriating if you don’t like tech. Those bloody steering wheel pads for a start...
Anyway, the Golf is badly soundproofed in the wheel arches. You’ll notice this the first time you go over a freshly gritted road. Plus if it has Bridgestone tyres they are quite noisy.
The suspension springs are quite firm on a GTI so no matter what your dampers are set to the springs will dictate the ride and handling. Unless you’re a continual fiddler who will adjust for each different road section surface you will need to find a damper setting that best controls the spring oscillations without inducing either car sickness at one end of the scale or sciatica at the other. Funnily enough the non adaptive dampers do this quite well
Too much choice can literally be too much sometimes. I’ve had the indigestion to prove it many a time when exiting a buffet restaurant.
