If all your documentation and processes are around CentOS, then staying with it may be easier. If you already take snapshots of the public repos and manage OS update change management that way, then nothing should really change for you. The same Dev/QA testing processes would work with CentOS stream and you should hopefully catch and surprises prior to production using your existing change management processes. That is just my opinion based on change control and patch management experience and based on conversations with other organizations. C7 will be EOL in 2024 so you have time to figure out your path.
