I wouldn't go with One Handed, two spell types
and Block unless you're more than happy to switch to a shield every time the enemy is at close range (which will be a lot). The concept of healing in left hand and weapon in right hand is tried and tested, and it works, especially with heavy armour to give you that much more defence.
An Imperial is the obvious choice - the +10 to Restoration will be nice at early levels, and will let you perk the skill after the very first level. However, I would suggest that you go for some originality, and be an Orc. This is why:
- +10 http://www.uesp.net/wiki/Skyrim:Heavy_Armor
- +5 http://www.uesp.net/wiki/Skyrim:Block, http://www.uesp.net/wiki/Skyrim:Enchanting, http://www.uesp.net/wiki/Skyrim:One-handed, http://www.uesp.net/wiki/Skyrim:Smithing, http://www.uesp.net/wiki/Skyrim:Two-handed
- The 'Berserker Rage' power.
All the skills there are ones you mentioned, excepting Two-Handed. It would mean you'd have to briefly concentrate on raising Destruction and Restoration, but 1) it would make for an extremely original character, 2) the +10 to Heavy Armour (arguably the slowest growing skill you've mentioned) will keep you safe and allow you to train both Restoration and Heavy Armour in its damage-tanking capabilities. The Orc power makes you deal double damage, and receive half damage, for sixty seconds. In exchange for a little bit of work regarding magic, you gain access to the best racial power in the game, instead of the Imperial option - calming someone down for a bit.
