Why don't you try becoming comfortable with Linux while using it in a Virtual Machine? I tried different distros too, and then I decided which one was the best for me.
We can't really suggest you one, if we don't know what you are going to use it for.
You may want to do some research, because different distros have different purposes (gaming, privacy, programming, easy to use etc etc).
https://distrochooser.de/ is a great tool that help to understand what the different distros can do.
Also, you should probably know that selecting a distro is more about selecting the underlying OS and less about the UI (DE).
Most distros support the top 5 Desktop Environments (DE for short). And selecting a DE can be just as important.
