Beat Saber is a must.
Also, Superhot VR and I Expect You To Die are really great games to start out with if you can find them cheap or don't mind pirating since they're both pretty short. Neither one requires any artificial locomotion, so they're pretty good for beginners.
I had fun messing around with Space Pirate Trainer too when I first got my headset, although I'm not sure that's really worth paying for.

>Alyx
I know Alyx was made to be super accessible to beginners, but I really think it should be played with continuous movement [spoiler]even if it wasn't entirely made with that in mind[/spoiler] and most people can't handle that right away. It's definitely worth jumping straight into if you can handle it though.

Supposedly really good. [spoiler]I'm too scared to try it though.[/spoiler]
