Did you install Windows 10 yourself from scratch? If you managed to do that you should be able to handle most Linux installs as well. I would go so far to say that generally Linux is easier to install than Windows nowadays. Go with Mint or OpenSUSE or Ubuntu and you should be all right.
If you have nvidia graphics that might give you trouble in the form of one extra package to install. If you have Intel or AMD graphics you shouldn't expect any trouble at all.
The biggest difference between Windows and Linux is that you generally don't download apps and drivers from websites but use your package manager to install stuff. Similar to app stores on smartphones. And unless it's nvidia all drivers are already built in.
You can download live Linux images that boot directly from USB to try them out without installing. Often the live image is the same one you can then use to install Linux, if you want to.
Not this. Mint maybe, even though their Desktop looks dated and is not Wayland ready. But OpenSUSE is strange (what to use, Leap? Good luck with outdated packages; Tumbleweed? Well you are now rolling) and Ubuntu is basically dead.
It's dead for hardcore nerds that care about such things as snaps and such. But in the corporate world, it's very much alive. I literally just got done installing an Ubuntu-based NVR from Wisenet for a store's CCTV system.
I definitely found Linux Mint the easiest version to switch to, coming from Windows. All the menus and icons were basically where I expected to find them. I couldn't have cared less about Wayland support, I just wanted to do basic tasks and for my printer to work, and Mint did that out of the box.
