I second the second idea. Adding a customizable label on Featured Content layouts would be HUGE. So that when they are rolled up you can get an idea of what is inside.
My idea would be to insert a new options on Text Fields INSIDE of flexible content layouts which could be a switch for “Use this value for Flexible Content label”.
So what I usually do is have a text field which serves as the header (or some other data inside the content) that would be perfect for using as the label of the FC block.
