I think we have an update coming to add an option to remove the title, I will let the developers confirm that. They can also tell us if there is something to be done with CSS about the featured image on mobile. I think that has to do with making the image work for parallax.
About loading images with text there, I can only hope that your listing owners will figure that out and choose a featured/first image that looks good up there.
You might give them a different image field for an advertisement or logo so they feel like they have a place where that will display nicely.
