Be more concerned with documentation - a good distro is backed up by good documentation to help you learn. Keep notes on what you learn - good to refer back to. Linuxlite is an example of distro that makes it easier for beginners to configure the system - with its pop up menu at the start, particularly when you need to install wireless drivers etc that require proprietary firmware. However as members have said any distro can be a good starting point.
it's just whatever suits your needs, if your a complete begginer the pop os/linux mint might be your best starting point and after that, maybe just use the terminal more to get the hang of it. but almost all distros are pretty good to start on
As others have already said it will depend on several factors 1. Is my hardware supported by the distro I choose?
2. Does it have the programs or are they easy to install that I will need to do my work/play?
3. Do I like the looks of the desktop that is does it please me?
For # 1 Best way to tell is by running the distro from a live session if everything works in live session then it's likely to work when installed.
For #2 Look at the installed programs see if they will meet your needs. ( Remember Linux is not windows and most windows programs will not run on Linux. Some will with programs like wine.) You may have to learn alternatives but it's worth the learning curve.
and For #3 only you can decide what suits you on the desktop try several different ones live KDE, Cinnamon, XFCE, Gnome or others see which one you like the best for both looks and functionality.
With all that behind you the choice should be fairly easy in the end.
Good luck in your search.
