Dunno what's so scary about Linux these days aside from the gatekeeping users, idiot-run orgs and obstinate developers, but things couldn't be simpler these days. And they were already pretty simple to begin with back when I started mainlining Fedora Linux for over a decade ago.
Picking a distribution comes down to three factors, in order of importance:
1) The packaging philosophy and range of the distro. Your mainlines typically have a seperate repository for proprietary software, but it's trivial to enable. Of course, this is useless if you don't have anything to pick from.
*2) The release schedule/upgrade philosophy. This one is key because it can be the difference between you receiving new software now, or five years from now. Long Term Service might seem appealing to the average user, but computers have plateaued, and I seriously doubt you're running a CPU obscure enough or hardware old enough to be considered for removal from the kernel. As such, I suggest if you are going to pick a distro with a long lifecycle, pick either mainline Debian or OpenSuse Leap.
2a) Yes, I know Mint and Ubuntu are typically suggested for new users, but I don't abide in their ungroovy "LTS of an LTS" approach, because it frankly keeps unsupported software running much longer than it frankly should.
3) The default desktop or window manager. This is actually unimportant, but while you figure out how to install another, you should at least,
tolerate the one you land in. Me? I'm a madman, and don't use a graphical session manager; opting for the Terminal Based Session Manager, and I have upwards of 10 WMs installed at one time.
3a) I tend to think Gnome is a poor choice for anyone getting into Linux with absolutely no shoes, because it's a very different paradigm aimed at lofty goals they (the Gnome Devs) never achieved. My suggestion for a starting desktop is the eternal rock, XFCE.
*2) Some people might suggest this is less important due to innovations such as Flatpak or Appimage, but I think it's far better to be able to configure and tweak your packages personally without having to install 12+ GB of runtime files for a small Xlib program.
