Welcome! I also have an Outback and I had exactly the same problem with air noise: it was a poorly positioned gasket at the level of the rearview mirror, easily adjusted with a little thin insulating foam. For the noise on the glove compartment side, I had to wedge the rear with adhesive felt, it was indeed a side game that hit bumps or cornering. Nothing serious, but annoying, I understand you! Otherwise, great car, even if the consumption stings a little in essence.
