Since RHEL 8, Red Hat offers 5 years of full support and another 5 years 
of maintenance support [1]. I'm no expert on the difference, but to my 
understanding only high priority issues will be fixed at Red Hat's 
discretion during maintenance support. The last minor release of RHEL 8, 
which marks the end of full support, is scheduled for May 2024 [2].

So, yeah, I was wrong saying RHEL 8 is going EOL in May 2024. But since 
RHEL 9 is already out, I'd go with that. In the same fashion I will 
shortly upgrade from Fedora 35 to 37, skipping 36.

Since CentOS Stream is a different beast all together, Rocky 9 (or any 
other RHEL clone version 9) would be my choice when upgrading from 
CentOS 7. For a fresh install, I'd definitely consider CentOS Stream 9.
