Would it really hurt this show to have Superman without the stubble? Too often they make him look more like a hobo.
In the comics the fortress was always more interesting pre-coie than post. For one thing it was actually Superman's fortress. Not Jor-El's. Nor was it a gift from the ereadicator. Also it was not destroyed at the proverbial drop of a hat. Though it would have been logical for Kal to have upgraded the traditional fortress into a tessaract/hypercube.
