I read man install, and it seems that it just copies files with ownership & mode. So, is install a shortcut for cp + chown + chmod, or does it do more, under the hood?

@JdeBP It is because I readman installthat I was hesitating if there are benefits of using it vs. using cp chown chmod.

Unless $ which install tells you that it is a shell built-in, install shouldn't be some sort of wrapper to cp + chown + chmod.
The man page reveals that GNU install has a few extra options, like -s, which strips symbol tables to save space. I'm not sure that this can easily be achieved with cp + chown + chmod, as this doesn't seem to be mentioned on any of their man pages.

There are a lot more differences than even that. Don't forget the-doption, and its subtle difference tomkdir -p. Then with BSDinstallthere are atomic copying, all of themtree-related functionality, and the various link-instead-of-copy modes.
