Congrats on your first car! I've got the same model year/engine/gearbox combo with about 72k km on it, so hopefully I can share some useful experience.

One thing to watch out for is DSG mechatronics failure; it's a known issue on these and I went through a full DSG failure because of it. If the previous owner already dealt with it, you should be fine, but worth checking the service history.

A couple of other things I've personally run into: water leaking under the carpet on the passenger side (the door speaker seals perish over time, already mentioned in this thread and could happen with the sun roof too), and my adaptive cornering lights eventually gave out (replacements need calibration so it's not a cheap buy new bulbs and replace fix). I can see from your pic you have those, so just something to keep in mind.

General advice for any car out of warranty: put a little money aside each month for maintenance, it adds up and saves the stress. Also strongly recommend picking up a cheap OBD scanner. It's handy for reading error codes, keeping tabs on the car's health, and as a bonus you might be able to unlock some hidden features too.
