Of course!

Marianara sauce: https://cooking.nytimes.com/recipes/1015987-classic-marinara... You'd have to buy a san marazano can and spaghetti for this, a couple bucks each, and you can store each for quite a while. You can add meatballs in it if you're not a vegetarian.

Pesto sauce: https://www.seriouseats.com/recipes/2014/07/best-pesto-recip... You might balk at the idea of having fresh basil... I would argue it's one of the things you really need in your life! Buy a small plant, it'll run you 3-4 dollars (if that). Keep it by your window sil so it gets some sunshine, and it looks pretty, and the responsibility of having to water it is calming and enjoyable.

A whit'ish sauce: https://lilluna.com/creamy-garlic-penne-pasta/

It really gets fun when you get fancy with it. I often add whatever vegetable I have at hand (e.g. , get some cumin seeds and bay leaves heated up in some olive oil, add some onions/garlic into this oil... and whatever spices you like and can handle (I'm partial to a bit of cayenne pepper, paprika, ground cumin), and finally add your $VEGETABLE). Add this to your pasta sauce.

Non basil pesto is also amazing. Some of my faves are with flat parsley (more spicy notes), ramps (not in season right now obvi), and mint pistachio

Also Spaghetti Carbonara is super-easy if you're OK with bacon :-). Can also toss in some quickly defrosted frozen shrimp to many recipes. A lot of quick spaghetti recipes.
