Are there ready-made sets of premium panels, settings, levels?

Question

Unity

Many games have very similar settings panels (sound, language, etc.), level selection, premium panels (disabling ads or buying some in-game items).
Are there ready-made kits somewhere?
So that you can change some pictures, icons, but the principle itself has already been debugged.
Maybe somewhere they are, I don’t know yet, advise if there is somewhere similar.
