This is obviously not as fully featured as what you’re asking for, but if you want an easy way to embed Google Photos into your notes, this is what I do.
It lets you take a Google Photo link, and add it to a note as either:
a text link
a thumbnail with the image data hosted externally on Google Photos
or a thumbnail with the thumbnail image saved locally in your vault.
Clicking any of the above will take you to the fullsize photo in Google Photos.
