No offense, but alot of fols ruin good meat with marinades, rubs, spices, etc.
Buy the best meat you can find. Coat it with just a bit of olive oil, then some sea salt and fresh-cracked pepper. THAT IS ALL!
This allows you to actually taste what beef tastes like.
Sides would be some kind of potato, a wedge salad. Peach dump cake with home-made vanilla ice cream for dessert.
