If I were to find system perl to be 5.8, then I certainly would try to install latest version available.
There have not been any significant changes for me to chase the latest version. So current default package version, 5.32.1, on FreeBSD has been fine by me; default of 5.26.3 on Rocky Linux 8 is not bad either. Any version currently being maintained, thanks to cavac for reminding me to be particular about the maintained version, since 5.16+ has been good enough.
Then again have not been using Perl as much since ~2017, none for work, so🤷🏽♂️
