There is no difference between Goblins and Orcs as far as being different species. They are basically the same. If I had to name one difference it would be that Goblins are a type of Orc that has developed more to tunnels and caves, whereas Orcs I think of more patrolling in open spaces, such as the plains of Gorgoroth.
Orcs are great warriors, Companions would seem attractive to her... and she doesn't know the end result of that venture yet, and it can be cured. Orcs are also pretty epic Smithers as well, so perhaps she could sell her craft. Visit all the strongholds, there's always something to do there.
