How does the generality of overture compare in different schools of classical music? Is it higher?

Overture is the music played before the opening of classical opera. Many composers use the main aria or theme, dominant motivation and other materials in a play to create in sonata form or other forms, so as to be familiar with the music of this opera from the beginning. It can also be said that a good opera overture is the essence of an opera. From the late classicism to the present, there are still many composers who create musical works in the form of opera overture, which is completely different from the original overture and has become an independent genre of instrumental works.
