I completely agree with your points.
I give new RPG players an introduction adventure with some friends to get them started.
That way I can also find out what they enjoy.
In the past I’ve had players start out in a bad way, they usually don’t stay.

RPGs should indeed play their strengths compared to video games:
complete freedom, role playing, cooperative storytelling, etc.

You make a good point in running an introductory adventure for regulars.
I think I’ll try it, it’s also a good chance to try out other RPGs.
