I'm a neanderthal. I barely know how computers work. I switched to Linux mint cinnamon a couple months ago. I'm a light user, mostly using word processing, internet, Foundry VTT to run games, and some light gaming via steam. I watched some YouTube videos and read some articles and just kinda sent it. It is offensively easy. I see no reason to go back to windows.
There are some things that take getting used to, but the user interface is really similar to windows and I would argue is largely more functional.
This video and this article helped a lot.
Remember, I am dumb and I did it. You can do it.
The current argument is "you give your SSN, address, salary etc to the bank, your employer, the DMV, etc. They all want something from you. The world's richest man doesn't need your money, so why are you afraid of giving him all your information?"
It's basically "if you've done nothing wrong you've got nothing to hide" but with your identity and life savings and social security.
