Use Ubuntu/Kubuntu LTS , do not upgrade every 6 m0onths to get the latest bugs from upstream just because they GNOME/KDE made some small improvements for some feature you probably do not use. There are PPAs with latest kernels and NVIDIA driver if you really need to upgrade for your work or gaming. This shit on upgrade happens on cool distros too, just Google Arch broke on update and you will see that there were cases where the efi partition was deleted and the user data was lost or some font customization a dude done to GNOME broke the login after an update.

If you want to install Linux to a less tech person you install an LTS distro and enable only the security updates, you can install Firefox from upsteeam and it has auto update and install ad blockers on it but teach the user how to stop it for specific websites in the case the blocker breaks stuff.
