From my experience, download many distros from Linux Mint to Zorin, maybe Fedora and OpenSuse if you want something non Ubuntu bases, or Manjaro and Endeavor OS if you are up for a challenge.
Then install them in a Virtual Machine like Virtual Box. This way you can test which OS you like, and see if the software you want works.
In my experience the Desktop Environment makes the biggest impact on your user experience.
Followed by the package manager (app store)
Then available software (steam lutris libre office)
Finally the terminal for when things go south (or you installed arch)
