CentOS Stream 9 will follow RHEL 9 and will always use a 5.14.0 kernel for as long as it exists. If you've run `yum update` and that's the latest version installed then it probably is the latest.
CentOS 8 died a premature death at the end of 2021 - migrate to Rocky/Alma/OEL/Springdale ASAP.

CentOS 5 and 6 are dead, do not use them.

Timestamp on mirror for that package is 2022-06-13. "Very recent", I'd say. (And the latest that there is.)

Whats the kernel merge/backport strategy of 9-Stream?

How can I try the latest new features that commit to 5.18 or 5.19? On 8-stream I can upgrade the latest version of the kernel via elrepo

A Stream is a development branch. A "trunk". About twice a year Red Hat forks a release branch from it, polishes, tests, and releases a RHEL point update. Afterwards the release branch gets fixes until next next point update is released (and for EUS branches a bit longer).

The Stream 8 is the development branch for RHEL 8, and Stream 9 is for RHEL 9. Therefore, the kernel in CentOS Stream 9 has features that probably will show up in future RHEL 9 point updates. What Red Hat backports to RHEL 9 kernel is up to them.

ELRepo kernel is not an "upgrade". It is an alternative to distro's own kernel. If you want similar alternative to CentOS Stream 9, then you should contact ELRepo. They probably will at some point build for Stream 9 too, if they already do build for Stream 8.
