What is Priority Image?

It is the first image considered when WPSSO gathers image information for meta tags and Schema markup. See here for more info: https://wpsso.com/docs/plugins/wpsso/faqs/how-does-wpsso-find-detect-select-images/

Also see https://wpsso.com/docs/plugins/wpsso/faqs/why-shouldnt-i-upload-small-images-to-the-media-library/ for additional related image information.

The relationship between thumbnails and metabox fields is not clear.
If Full size 2400x1600px
boobs.jpg
Then the following thumbnails are generated:
boobs-300x300.jpg (Woocommerce_thumbnail)
boobs-600x400.jpg (Woocommerce_single)
boobs-1200x628-cropped.jpg (WPSSO-thumbnail, WPSSO-opengraph, WPSSO-tclrgimg, WPSSO-cmcf)
boobs-1200x675-cropped.jpg (WPSSO-schema 16×9)
boobs-1200x900-cropped.jpg (WPSSO-schema 4×3)
boobs-1200x1200-cropped.jpg (WPSSO-schema 1×1, WPSSO-gmf)

Questions:

If I select image ID in Priority Media, will WPSSO itself determine which set of images to give to social networks and Google?
Will each social network receive an image of the correct proportion (or size???) when inserting a link to a specific page of a WP site?
Facebook Post will get boobs-1200x628-cropped.jpg?
What will Twitter Post get?
boobs-1200x675-cropped.jpg or boobs-1200x628-cropped.jpg?
Does the social network itself choose the preferred image or should I control it?
In the Image URL field for Twitter Summary Card Large Image, should field contain a link to boobs.jpg or boobs-1200x1200-cropped.jpg or boobs-1200x675-cropped.jpg or boobs-1200x628-cropped.jpg ?

The Image URL field for Schema Markup and Google Rich Results should contain a link to boobs.jpg or boobs-1200x1200-cropped.jpg or boobs-1200x900-cropped.jpg or boobs-1200x675-cropped.jpg or boobs-1200x628-cropped.jpg ?

Priority Image — is it about Schema Markup or about Opengraph?
Does Google use the “Priority Image” field or the “Schema Markup and Google Rich Results” field?

When the browser opens a page from a WordPress site, it receives scrset. But which of the images of this scrset will Google choose to present in search results, for example, an article?
And for Schemes such as ImageObject and CreativeWork, what wordpress thumbnail will WPSSO give as the Thumbnail Property? 1200×628 or Full size? What has higher priority in this case – the Priority Image field or the Schema Markup and Google Rich Results field?

Wpsso-thumbnail (1200 x 628) is about Thumbnail Property isn’t it?

Why is Wpsso-opengraph 1200×628 but not 1200×630?

I understand. If I select an Image ID in Priority Image, the correct markup is generated for all cases. But only if a full set of thumbnails has been created for a sufficiently large image.
