Unfortunately I can’t send you page URL because the website is still offline. I can send screenshots, if you need them.
have you tried the option “Featured image size”? please see the screenshot

Please note, there is default thumbnail load from “Media source” option, you can add extra thumbnail from layout editor.
I’ve tried, and the image goes full-width in that case, but then I removed any “Media source” option: I need to customize the link of the image with a custom class, and I do not know how to do it with the default thumbnail load. Only the thumbnail from layout editor allow me to do it.
Thank you very much for your answer.
