Civics are compact (small) sedans, Accords are larger midsize sedans. Accords can go pretty high for seating position though.
If it helps you at all, I'm 5'2 and my first car is my 2010 Accord sedan. I have my seating position as low as it goes and I can see just fine, if I go much higher it can obstruct my view of my dashboard and speedometer.
Edit: the size of the car that you'll want to get depends on what you're willing to sacrifice. Midsize sedans get fewer miles per gallon than compacts, but they are more protective in a crash. By that same token, compacts get more miles per gallon, but are less protective in a crash. Safety ratings only apply to similarly sized vehicles- a small car getting high safety scores doesn't mean much if the small car is being hit by a large minivan.
