It's an understandable issue - the game world is huge and reasonably fleshed out considering its size, but the gameplay is incredibly dull unless you find creative ways to twist it into something more entertaining.
I'd argue the best method of combat is using magic and sneak liberally, as a sort of manipulator - the AI is not fun to fight head on, so don't bother. Use illusion, conjuration, sneak, and archery. The end perks for each should look something like this -

Add the crafting skills in at your leisure for optimal durability/damage and you end up with something like this -

Stealth, archery, magic aren't exactly well implemented but they're in a better place than melee.
You can completely ignore non-combat skills without missing much, but the best ones to pick, for convenience, are probably these -

Maybe add bribery in there if you want to steal a lot for whatever reason - it's not particularly rewarding and the crime system is so dull it's trivial emptying everyone's pockets but whatever floats your boat.
As for roleplaying, I feel like ignoring it is a good way to start the game while you get a feel for everything else. Screw around and figure everything out first while you learn how the game works and how it doesn't. Some elements of the game just aren't very conducive to attempting to seriously roleplay anything, and you can end up very bored if you're trying to role play a character that's focused on any the less complete elements of the game.
