Congratulations on living the High Life. I'm drinking one right now, as a matter of fact. We just got the Louis Vuitton-styled tallboy cans at the gas station, so I'm guessing that the red white and blue ones are at the end of their run. The biggest I've seen though was 24oz. I think a 32oz can might be just unwieldy, but then I'm not six feet tall.
Spaghetti: remember that you don't need to use tomatoes, but if you use tomatoes, go for fresh roma or canned san marzano. If you use mushrooms, don't use boring white or button mushrooms, get something with character, and mutilate it to all hell while BROWNING BEFORE ADDING TO SAUCE. Cook your tomato paste to develop its flavor. Use fresh herbs if possible, and if not, squeeze your dried herbs to crack them a bit, which activates their remaining oils and brings out their essence. You might have had some wild boar in that sauce, in which case good luck approximating the flavor, there is absolutely nothing like it, except maybe rabbit done just perfectly right. Then again, they have different breeds of everything over there, including cattle, so it may have just been a regional beef variety with some special curing. See if your local gourmet shop has Bresaola (like a beef version of prosciutto), that'll pack a nice punch in a sauce, especially if you don't have them slice it thin and you chunk it up yourself.
Most importantly? Keep experimenting and figuring out what you like and dislike in your pasta sauce. I go for bay leaf sometimes, cumin usually, and paprika, in addition to the standard old oregano and basil. Sea salt vs kosher salt, that's a fun tasting experiment. And here's the thing: if it turns out bad, it's just one pot of food, a couple meals that can be easily replaced by a $7, 12" grocery store sub.
True story: we were going to make tostadas tonight, and as we were gathering all the ingredients I realized I didn't have any beans to refry or even cheese for topping. I said "hey don't start that oil for those tortillas, we don't have beans to refry or even cheese for topping." Mrs|choop looked at our romaine, ready to be shredded, and our heirloom tomatoes, ready to be diced, and our avocados, ready for slicing, and said "screw it, how's Taco Bell sound?" and I said "good enough" because if it can't be right, I won't be picky.
