Featured image on pages and posts

Hello there, I'm using clean fotografie free. Is there a way to set the featured image not to appear in the page/post itself? I want it to just feed the posts list, hero content, featured content, etc, not to show in the top of the actual page or post. And when I set up a page with a block that presents a list of posts from certain category, and check the option "Enable featured post" in the block's settings, the featured image of the featured post is cropped to a wide and short ratio. Is there a way to bypass this crop and show the image in its original ratio size? The website is in maintenance mode, thus not avaiable, as I'm working on the new version.   Thank you, and best regards
