The only way to win D&D is to have fun. For some people that means cookie cutter builds, for others not so much.
I think most of the obvious candidates for classes matching your solicitation have been stated already.
I also think that any race-class combination is perfectly viable. In a game I ran just between me and my two nephews, their eyes lit up when they saw Dragonborn as a race option. Then at class selection, they chose rogue and wizard. I began explaining how ability scores and racial modifiers would play into their choices, and it didn't bother them. They both won D&D.
Feats? I've heard not so nice things said about Savage Attacker. It's statistically worse than Great Weapon Master in terms of raw DPR, but then you'll never have to groan when your -5 causes you to miss, so that's cool. I'd still sooner take ASIs for my attack stat before SA, though.
