I want to grant a user sudo access.

I suppose mainly I want to grant privileges to install software, and am not quite sure how to this in CentOS:

https://linuxize.com/post/how-to-add-user-to-sudoers-in-centos/

wheras in Ubuntu the syntax is, as I recall at least:

sudo addusr foo sudo

to add user foo to sudo. I'm also curious as to why this isn't available in CentOS -- perhaps it's not fine grained enough?
