I find fettuccine a better use in every way if your dish requires straight pasta (not a huge fan of angel hair). Rotini is the shit when you have a sauce that is chunky but I also use it in mac and cheese - whenever I can really. Honorary mentions to cavatappi and penne as they do a great job of soaking up that sauce with their crevices. Them saucy crevices.

Along the east, rice noodle vermicelli is fantastic; much preferred to any angel hair any day when you can use a rice noodle. Kuey Teow noodles (flat noodles) I can gorge my weight on when prepared correctly. And do not overlook a good egg noodle in a killer broth.

This is in no way an exhaustive list but I find all of these easily in US cities!

If looking to keep the general spaghetti form, bucatini can't be beat.
