My understanding of safety concern around Linux is mainly the security, namely, full disk encryption. Full disk encryption avoid an attacker unplug your harddrive and directly read the data.

While it is possible, it is definitely not easy to setup right, particularly if you want hibernation to disk properly setup. There is certain requirement on the disk layout setup, use LVM, setup TPM, setup bootloader parameters, setup hibernation and wake.... any step is wrong you have to use a boot drive to rescue, and it is very hard to fix if you don't have LVM in the first place. For example, Arch Linux's archinstall won't setup this whole suite for you.

This is really nessary if you are going to take the computer outside and it might get lost stolen. You definitely don't want other people to read the content after it was lost. I think this kind of security is default on Windows / Mac / iOS / Android right now already, but Linux is still so hard.
