From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

It's very nice to not have a dozen different versions of the same distro to parse through and figure out that are simply the same distro with a different DE. Moreover, very few of them offer this many options.
Cachy could be doing a better job explaining what the user is looking at here and who each of these is for. Pretty easy to sum up in 1-2 sentences...
The reason most distros don't do this is because they usually try to steer users to their preferred desktop. I don't mean that in a bad way, but often they call it the flagship edition. This is usually the desktop environment that they develop and test. Think Linux Mint with Cinnamon, popOS with Cosmic, Zorin, etc. Pretty much every other distro that has options do exactly what you are showing through the use of the venerable calamares installer that you see in your screenshot.
They don't though, they just offer a dozen different options that are offered as entirely different "distros" with no explanation of what they are. Look at the Linux Mint page. You click download and you're presented with 3 options with no explanation of what they are, which one you should choose or why.
Have you actually visited the download page that you linked? Because it has screenshots, explanations, whole nine yards.
