I have ran selinux in production on rhel and centos for years, had very few problems. All packages that are maintained by red hat comes with selinux policies included, over time stuff barely changes, just some security fixes applied.
In case you have trouble, just install (setroubleshoot-server) and run sealert -a /var/log/audit/audit.log and it'll inform you whats needs to be done, i.e set a sebool or generate a policy. Solves 95% of the problems.
