I'm going from stats on this one and a little bit of canon Nord as well. Nords statistically are better Sword and Shield Warriors over Two-Handed Warriors. The Nords also have a deep hatred and fear of anything Elven or Magic so I'm thinking the Nordic people would not have anything to do with Daedra or the College of Winterhold. The Companions are the only guild that the Nords like because it holds to the morals of glory, and honor. But this is how I suggest building a "True Nord" character.
1. One-Handed - Swords and Axes seem to fit this build better.
2. Block - Since Nords represent the Norse culture in the Elder Scrolls shields and axes are essential.
3. Light Armour - This fits the build a lot better than Heavy Armour because you can close in fast on your target and not drain all your stamina in combat.
4. Archery - Nords do a lot of hunting for there food so I would expect them to have some skill with a bow, you can dig into this skill if you want but I see it more as a secondary skill.
5. Sneak - I would only use sneaking when raiding a camp or stalking a deer so its not really a major skill but still fun to use at times.
6. Smiting - Now I don't use smiting because of my character Role-play I'm doing, but you can use this skill if you want.
If you have any more questions let me know and I hope this helps you out.
