To be fair, testing in a VM is for seeing the basic fundamentals of the OS. Ok, let me try to help with a couple of things then.

For finding you distro:

1. Find your favourite environment. Is it GNOME, is it KDE, Cinnamon, maybe it's Xmonad or dwm? There are a lot of these and you should test this first. Distro doesn't really matter in this step. Just find one with the desired environment and test it in a VM.
2. Once you find your perfect environment, find out if you want a really stable system or something cutting edge? Maybe something balanced in between. Distro still doesn't matter in this step. Once you decide what you want, now you can find distros that suit this.
3. Choose you favourite init system (Optional). Some people like to control what's under the hood. Just note that, not choosing systemd will filter a lot of distros here. If you don't care what's under the hood, skip this step.
4. Now you have narrowed down to possibly 3-10 distros. Still a lot. However this step is where you choose your favourite package manager. If you don't care about the mechanism, just pick one you liked from the default installations of them. If you are using Linux for some time, you might already have a favourite package manager.
5. Congratulations, you have found your distro. Just use it and see for yourself.
6. Wait, it might still not be the correct one. However you cannot know this without using them daily. Some people stay with what distro they start, some people distrohop a lot and settle on Debian. And some other love their niche distro that works nicely for them. Stay with what really clicks with you.
