Sporty or Fuel Efficiency sedans for preferably 50k or less?

I can’t decide whether I want a sedan that’s sporty or more fuel efficient, so how about some options for each category? Current plan is to wait till the newer models for this year come out, to either get something brand new or possibly save money on the current or later gen stuff.

Beyond that, things that would be nice to have the option to add on are enhanced audio, 360/panoramic view cameras, and ventilated + heated seats.
