Sleeves: Showing a touch of shirt cuff is best and the sleeves should allow this (and double/French shirt cuffs will look better than button cuffs). Really fine jackets will have "surgeons' cuffs", which is where the sleeve buttons actually work (not just for show) and allow the sleeve to be rolled back. There is a tendency for people to have just one button (usually the one closest to the opening) unfastened just to show off that they are wearing a "proper" jacket. Those who always wear proper jackets feel no need to show this off, because of course their sleeves are "working", and so are content to have? all buttons fastened.
