If you set "Featured Image Placement" to "Title/meta background image", the image height is displayed very small. Use the modules top/bottom
padding to show more of the image. Preferably like 15vw (viewport
width).
If you set "Featured Image Placement" to "Above Title" or "Below Title", the image is displayed at 100% width to make it responsive. It keeps the aspect ratio, so the full image is being displayed. If you only want to see a smaller height, you need to use an image with the size/aspect ratio you really want to see. Alternative is using max-height in css, but that scales the image down with the correct aspect ratio, and then it displays 100% width of the screen due to which the image is horizontally stretched.
.et_pb_title_featured_container img {
max-height: 400px;
}

Or use a css class on the module and then the following css
.mycssclass **img** {
max-height: 400px;
}
