As someone who switched to linux full time last summer after trying it over and over again every few years for the last few decades (ugh, I’m old), I can say that it’s WAY more user friendly and easy now. It used to be a hobby. Now it doesn’t have to be if you don’t want it to be. It can just be an “install it and forget about it” tool.

There are some distros that are more user-friendly than others. You can (and should) try them out via “live disk” before installing. I was going to use Mint, one of the most often recommended distros for Windows transplants, but it didn’t like my laptop and kept freezing, so I’m glad I tested it. For the record I ended up using Pop_OS! since it works great with laptops with hybrid nvidia graphics. Not my favorite of the distros I tried, but the most reliable on my hardware. Glad I tried a few.

And yeah, sounds like you have more than enough computer smarts to figure out any random issues that may crop up. I wouldn’t worry about it at all.
