Rocky is going to be exactly what CentOS was: a free version of RHEL. The reason you would use this vs. Debian or Ubuntu is because you've got systems that need to mirror your production, but you don't want/need enterprise support on them.
When I worked for a hardware vendor we had customers who ran hundreds of CentOS boxes in dev/test alongside their production RHEL boxes. If there was an issue with a driver, we simply asked that they reproduce it on RHEL (which was easy to do). If they had been running debian or ubuntu LTS the answer would have been: I suggest you reach out the development mailing list and seek out support there.
Whether you like it or not, most hardware vendors want/require you to have an enterprise support contract on your OS in order to help with driver issues.
