This is a demo script. As noted in my introduction to the script there is a very odd delay when Apple Notes makes a new note from an imported RTFD file (or RTF) and images are embedded in the text as desired. At first it seems like nothing happened. A minute or so later the images just show up. Go figure.
NO – I have no idea if this works with your data. But it is a starting point if you want to fiddle.
Out of curiosity, though I wrote a script to do what the OP wanted (because I could) I wonder why one would want to export notes to Notes when we have DEVONthink to Go? Not sure what the use case is.
