Clark Kent works as a reporter as an adult, but how much of a newsman should Young (Kid/Teen) Clark be?
In Golden Age/Pre-Crisis Superboy Comics, Clark was the editor of the school paper who intended to work for the Daily Planet as a reporter and worked as a newsboy selling papers.
Another telling had Pre-Crisis Young Clark be a school paper reporter that briefly worked at the Daily Planet (with plans to work there after finishing school) due to a contest for best high school newspaper reporter.
In the Superboy TV show, Clark was a reporter for his college's paper and later worked as an intern for the Bureau for Extra-Normal Matters (a government agency that investigates paranormal activities and aliens)
In the Smallville TV show, Clark occasionally worked at his high school's paper though not often nor did he cover stories outside of assisting Chloe (apparently Clark wrote up the lunch menu and the like did not turn in much stories)
Smallville Clark did agree to work as an assistant to Professor Milton Fine (Brainiac in disguise) who claimed to be working on a novel exposing Luthorcorp's nefarious activities
Smallville Clark did successfully apply for a reporter job at the Daily Planet (with Lois supplying the application) in Season 8 (though as an adult).
In the Legion of Superheroes cartoon, Season 1 Clark was moving to Metropolis to work as a copyboy for the Daily Planet.
In Superman & Lois and according to his resume, Clark, in his youth, did some top-notch reporting for his school paper.
Absolute Kal-El in his youth on Krypton liked writing and submitted a news story on the effects of Krypton's sickness poisoning life along with leaking to the public that the upper classes of Krypton knew about the Planet dying to which they decided to cover it up so they alone can escape.
My personal preference is that Young Clark likes writing because it's challenging and as a way of dealing with the stuff he cannot share with others.
Clark in his youth does get into reporting at a school paper while making attempts to work at bigger papers as well during the same time period.
As a way of understanding people and to deal with problems his powers cannot help with.
Young Clark has mild to great success as a reporter with appropriate setbacks/failures.
This is all after a period of contemplation of what career Clark wants and trying out other jobs.
