It seems to me that the new Anaconda Web UI installer leads to some extra packages being installed in a fresh install of the F43 KDE variant compared to previously. All of the following are on my new laptop, but not on my (upgraded through the years) desktop.
I searched for the files you listed in my F44 Kinoite, which also uses the new webbased installer, and I don’t have the files.
So, either there is a difference between the KDE and Kinoite version, or between F43 and F44.

So if a live image includes the Anaconda WebUI, it will have cockpit packages installed. And presumably those end up in the installed system, since the install (for non-atomic Fedoras) essentially copies the content of the live image.
