A jack-of-all-trades "Adventurer" comes to mind. Prefers to fight with daggers and sneaks around dungeons in light armor. Knows how to heal herself, keep her gear in good shape, and how to get through locked doors and chests that are found in the many caves and ruins around Skyrim. But as previously mentioned, it really depends on what you are doing with the character. Are you in the Thieve's guild or the Dark Brotherhood? Are you in the Legion or the Stormcloak army? Companions? College?. That's the beauty of the game - it's up to you.
