Post image before title

I would change the size that the theme crops the featured image to.

On line 73 in functions.php you can change:

add_image_size( 'typecore-large', 720, 340, true );

to:

add_image_size( 'typecore-large', 720 );

This will give your featured images same aspect ratio as the default image is (no cropping). Preferably you’d edit this with a child theme.

Hm, have you run the regenerate thumbnails plugin once after changing the size? https://wordpress.org/plugins/regenerate-thumbnails/
