I'm new to the TES series and it's becoming apparent to me after quitting 5 characters before hitting level 30, most before 15. This game loses it's flare or that feeling of immersion, unless you know what you want character to be, because there's simply so much to do. For me personally after I have spread out my perks, or just have to many ways of going about combat it's just hard to choose so I think Skyrim would be most enjoyable if you do define your character before you start, or quicky as you get into it. I'm an rpg noob, at least I haven't played any that really give you as many options as Skyrim does. So please post any Class/ Roleplay you have used or think would be a good idea. I will edit this post and try to organize all of them to help give less creative people some direction though their adventure in Skyrim.

Also if i'm being stupid and there is already some comprehensive list of play styles somewhere I don't know of feel free to direct me to it.

Paladin
Battle mags
Assassin
Thief
Destruction mags
Summoner
Two Handed Warrior
Shield and Board
Dual Wield
Archer

Something more specific that says what race, and the perk trees you would go into

Race is just for looks.
And perk trees are up to you. There are no classes. Come up with your own unique character and play it how you want. That's the best advice to give you. You can go on TES wiki to learn what each tree does. Im playing an assassin right now.

Breton

Skills:
One Handed
Archery
Sneak
Smithing
Enchanting
Light Armor

Breton Necromancer

Oh here goes a link which shows you all the skill trees so you can make your own guy. I'll link you my characters. Look at those, then reset the perks and make your own. Brainstorm a bit!

These are just what I like. Find your own style off of what sounds fun to you.

i started with a nord berserker - light armor and two handed weapons
then because of game lag... i turned him into someone with multiple personality disorder. this allowed me to continue my unplayable save with a variety of different options without losing the general feel of the original character. this might be a bit off topic but i think it goes along with maintaining the integrity of a character play style. uesp wiki is a good place to look at class ideas from past ES games.

Arcane Master - use anything and everything magical to your advantage, not relying on armor or physical damage. Which is basically what I do but I don't typically use summons cause I find them counter-intuitive to my playstyle and restoration I hardly ever use because I hardly ever take damage.

there isnt such a list, not even solid guide AFAIK.

but rule of thumb, especially playing on master, you should pick and stick to 3 core skills, core skills being the ones that you will absolutely put a perk on when you level and absolutely will have them at the required skill lvl for the next perk. (and do so untill at least 75 skill with those)

some setups I found very effective:

pure mage:
destruction-alteration(or illusion)-restoration core with crafting -> enchanting

battlemage:
Heavy armor-destruction-one handed core with crafting -> enchanting (if you prefer destruction for main damage) or smithing (if you prefer destruction mainly for supportive and ranged damage only)

Healer:
restoration-illusion-archery core with crafting -> enchanting

Ranger:
sneak-archery-one handed core with crafting -> alchemy

Soldier:
block-onehanded-light armor core with crafting -> smithing

Paladin:
2 handed-heavy armor-restoration with crafting -> smithing
