The beef in bolognese sauce adds depth, the pork in bolognese sauce adds fat and sweetness and veal adds a silky and smooth consistency to the bolognese sauce.
The best pasta for bolognese is hearty, flat or tubular pasta which can hold the rich meaty bolognese sauce like tagliatelle.
Tagliatelle is the most popular choice of pasta that is used for bolognese, although some other good pastas that are also good for bolognese are rigatoni, fettuccine and even pappardelle.
The wider noodles such as tagliatelle and pappardelle noodles have a larger surface area, which allows the bolognese sauce to coat and cling to every piece of the pastas.
You can use bolognese sauce for spaghetti, although the authentic version of the bolognese dish is served and eaten with wider and flat pasta noodles like pappardelle or tagliatelle, because the thicker pasta is better at holding onto the rich, meaty bolognese sauce.
But you certainly can use bolognese sauce for spaghetti or any other noodles that you prefer.
