If flavor isn't a consideration, you can simply choose the two skills that you desire, two tools/languages, get some starting equipment and work out a feature with your DM. This doesn't need "power gaming" to any degree.This. Skill proficiency is about the only thing that I use to consider what background to take in 5E; flavor is not a consideration for me. I can't believe it needs to be said in the first place, but I'll second "If any element of the game grants any mechanical bonus, it will be used power game.".
