I've seen the Sagrada familia, and it ain't small!

But colloquially, Sagrada Familia is what most people would consider a cathedral.
There can be, though it's not common: https://en.wikipedia.org/wiki/Co-cathedral
> Although known as the "Basilica of St Denis", the cathedral has not been granted the title of Minor Basilica by the Vatican.
A basilica on the other hand is an honorific title granted to some churches by the pope for historical/religious reasons.
An interesting note: Saint Peter in Rome, the most famous church in the christian world is not a cathedral itself as it is not where the pope has its seat, that's actually another basilica in Rome, Saint John Lateran, which makes it the most important church in the catholic hierarchy with the title of "Omnium Urbis et Orbis Ecclesiarum Mater et Caput", or "Mother and leader of all the churches in the world".
Saint John Lateran is also not in Italy [1] due to an extraterritoriality treaty in 1929, part of the same treaty that established Vatican City. By the way, that church is exactly 1700 years old this year.

In short, the "major" is reserved for four top churches in Rome. "Minor" is used to signal that the church is of significant importance, but not as important as the major ones. It's not related to the size at all :)
Seems like the four major basilicas have historical (maybe even pre-Schism?) associations, while the minor ones are designated by the pope.
