Do not cook sauce ahead of time. Cooking makes your pizza taste like spaghetti sauce. The sauce will heat perfectly on the pizza.
I usually drizzle olive oil over the sauce before adding toppings.
Want it really simple? Hand crush tomatoes then sprinkle kosher salt and drizzle olive oil. When the pizza is cooked, tear fresh basil and top pizza
While I agree with you that you don't have to cook your sauce, if it tastes like spaghetti sauce, there is something wrong with your pasta sauce.
Mark Iacono, owner of Lucali's, cooks his sauce because he says that's the way his grandmother did it.
Cooking it or not cooking it is a personal preference, try both and see what you prefer.
As for the OP:
Easy sauce:
Buy a can of Cento all-purposes crushed tomatoes. Open can, pour into a bowl. Mix in a drizzle of olive oil, maybe half a teaspoon of diced garlic, salt and pepper to taste. Spoon sauce onto pizza, put the rest in a container in the fridge or freeze for later. Add hot pepper flakes or oregano if you want, your choice.
Traditional sauce is just tomatoes crushed and blended until smooth, and some salt. You can add various herbs and spices to fit what you like, but there is no need to over-complicate pizza sauce. The dough and the toppings matter, the sauce is just one part of making good pizza.
