You can use the fedora direct sources to search their discourse forum. Google and Microsoft are likely warping your search results intentionally to drive you back onto Windows. Search is not deterministic any more. It is individually targeted.
I have never used KDE much, so I have no idea. You are probably looking for KDE settings. These would likely be part of gsettings in GNOME. That is not really a fedora thing. You need to look in the KDE documentation. This is the kind of thing that gets easier with time but can be frustrating at first.

By default it will break out many things. I use db as an extra layer of containers in addition to a python venv with most AI stuff. I also use it to get the Arch AUR on Fedora too.
Best advice I can give is to mess with your user name, groups, and SELinux context if you really want to know what is happening where and how. Also have a look at how Fedora Silverblue does bashrc for the toolbox command and start with something similar. Come up with a solid scheme for saving and searching your terminal commands history too.
