What about Centos 7 , what are the openstack releases that it supports ?

You have said that already. Train is the latest release on CentOS 7. -yoctozepto

As a centos 7 user I have many experience using this distribution however centos 7 doesn't support the newest openstack releases ( after train ) and centos 8 will soon lose the support from Redhat since it's EOL is scheduled for 31/12/2021 and the centos stream distributions are upstreams for RHEL therefor is most likely unstable.

So which distribution should I use ?

Use the one that you are most familiar/comfortable with and that is supported by OpenStack deployment projects.

For example, with Kolla Ansible, at the moment, you can choose from CentOS Stream 8, Debian Bullseye and Ubuntu 20.04 (sorted alphabetically; all have equal support). Soon, it will support Rocky Linux 8 as well (and then newer releases as they start coming).
