What specific security issues are you worried about?
If you're not sure, because you don't know enough, you're almost certainly worrying over nothing.
Install only things from the repos. Do not expose services to the internet (you will know if you're doing this, it will not be an accident.)
You can totally operate outside of those restrictions and still be secure, but for a new and anxious person those are guidelines that mean you won't have any issues.
Also, if you somehow think Windows or MacOS are better, just remember that they have as many security flaws or more, they just never get seen because the source is closed. They're unlikely to affect an end user too.
Do you have some kind of OCD by the way? Obsessing over your room being just right, obsessing over non-specific security problems.
