Regardless of opinion on where fights end up, they all begin stood up, and every unarmed attack i have witnessed or experienced has started with a punch or headbutt boxing guard is designed to deal with exactly these weapons. Add to that the fact that your training will involve lots of hard sparring,and the learning of footwork and sharp accurate punching and you have a very good foundation for self defense.
Examples always tell more about the individual than the methods used, but Lenny McClean, one of the most feared and respected underworld enforcers, renknowned for his unarmed fighting ability, was a boxer by style. The only 'ground game' he studied were the victims of his left hook lying on it.
