I’m thinking about my husband watching me use Mint. I am comfortable with the command line, I use Linux (and Powershell) professionally so I am quick to jump into the terminal to fix something. Everytime I do he complains that he could never do that.
There are still a few things you need to do in the terminal, like setting flatpak permissions - something many users will want to do - that would benefit from a graphical interface. Linux is almost as good as Windows or Mac in this regard but not quite all the way there.
SMS/MMS and the PSTN are completely compromised by multiple governments. Not saying that makes smartphones any better, just be aware.
