I could pose the counter question: Which aspect of the FR has a medieval feel to you? Plate armor and swords?Why do you say there is nothing medieval about FR? Compared to Eberron it certainly would be.
To me, the FR have mostly the atmosphere of the Western genre, just with swords and magic missiles instead of guns. You have these huge swathes of wilderness for exploration, old ruins of ancient civilizations, meet lots of wild tribes and animals, and even the ever present nobles have more aspects of a cattle baron than someone bound into rigid societal structures. All of this looks much more like the 18th to 19th century American West than medieval Europe.
