It sounds like the inner liner of one of your wheel wells has come loose and is touching the wheel. This would make a sound while moving, but not while stopped. Look inside your wheel wells for the plastic lining that goes all the way around the tire. Look for wear signs. It may even be a hole by now. If you see wear, tug on that wheel well liner to see if it is loose. If so, get replacement screws to hold it in place.
That would explain rumble sounds, high pitched sounds, changing sound when hitting bumps. And it would not affect any dynamics.
The creaking and groaning when car is turned off is a different animal. Possibly something to do with A/C which is depressuring after the car is turned off. To determine if that is the case, see if it makes the same sounds if you've been driving with the A/C off? If not, it's A/C related.
