One thing I'm not seeing much of in the comments, that I think is worthwhile to highlight:
Every single one of these icons should be available to choose by the user.
Some folks make good icons; others do not. Taste is highly subjective, and this applies to user interfaces moreso than user experience.
Interfaces should always be customizable; experiences should always be consistent.

They are. You can replace the icon of any app straight in Finder, in the Get Info window. Copy the icon from somewhere else, click the icon in Get Into to select it, and Cmd+V to paste.
I mean, you'll need to get the original icon, but that's not too much work. I don't think Apple themselves should be shipping every high-resolution icon they've ever used for every app. OS's are already large enough.
Ghostty is an example of a program that gives you a bunch of different icons to choose from and an easy way to customize it even further.
I don't know any other
