Some time ago I answered this question on a post that seems have been deleted but got some good feedback:
The most important decision as a new Linux user is the desktop environment, the most similar desktop environment to the Windows desktop are KDE Plasma and Cinnamon. This means your best options are:
Linux Mint (Cinnamon): They are the creators of the Cinnamon desktop environment and will be the default on installation.
Kubuntu (KDE Plasma): This is Ubuntu’s official KDE Plasma flavour, it comes with everything as usual just different desktop.
Fedora (KDE Edition): Same story as Ubuntu here, only that with Fedora’s own packages and environment.
First I would check if the hardware is compatible (99% of the time is). Then I would check what software you need and/or want and check if it is available at these distros, and get familiar on how to install the software packages (either with their respective app stores or in the command line).
There is a lot to learn but with these distros you can just install, forget and simply keep using them for eternity.
The last and more important tip I have is to not to worry about the sea of options out there, you will not be missing anything huge by picking one or the other. Which is how most of new users feel (I did in my time).
