Spy x Family became a massively popular shonen anime because it blended a colorful variety of genres and themes into a single narrative that anyone can enjoy. On the face of it, Spy x Family is a Cold War-inspired spy thriller with political intrigue, but it also has strong comedy and action elements. In fact, Spy x Family can compete with any action anime out there, even though it's not a "pure" example of the action genre.
