I highly recommend EndeavourOS for Framework users. This distribution is an Arch derivative with a graphical installer, tools like NetworkManager, and sane defaults chosen out of the box. You also get your choice of installing one or more Desktop Environments together at install time. The Arch wiki documentation is second to none in my opinion.
Once upon a time Ubuntu might have been easier to install and use, but now I believe that Endeavour has surpassed them. A friend who has never used Linux before was even able to install it themselves.
Once they have, you'll be able to view a graph of their reputation gained over time.
Here's a preview of what the graph will look like:
