I misunderstood your meaning about the PATH but I understand now. you're referring to the default path defined in the shell.
The Bash man page says, "The default path is system-dependent, and is set by the administrator who installs bash.", (so the CentOS packager?), and then continues on with "A common value is ``/usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin:/bin:/sbin''." That covers putting the script in /usr/local/bin, but then, that might not be what's on your system. On the CentOS 7.9 system I am working with, the default is:
/usr/bin:/bin
As reported by a very simple cron job that writes PATH to a file in tmp.
For cron jobs I usually use the full path to the script in the crontab then set and export the PATH in the script itself.
