Post mount would only make sense if you’re going for a flatbar setup indeed. If you’re using a drop bar I’d look into flat mount as you’ve got a lot more options available that are suitable with sti / ergopowers use.
Completely agree with you but in all honesty this is a city bike/hybrid because that is what i'm riding and the chances of me using a drop bar on it are really slim.
