Hi, Welcome to the Club.
If you stand outside your car, can you replicate the creak by pushing the top of the door? Is it alot better if you just crack the windows open a fraction?
If so, the outer weather seal probably needs some silicone spray applied.
Mine drives me mad at times, Ijust turn the Music up a little.
