So what is an easy to use or no think thing I could use a pi 5 for?
It sounds like you really want something that works "out of the box," in which case, I would look for projects that have disk images available.
This severely restricts what you can do with it, and as others have mentioned, is a bit antithetical to the Pi's original purpose as a tinkering machine. But you may find something you like.
The most basic would be to just use it as a desktop replacement.
