Converting first to a more limited format and then to KFX can certainly work around some conversion problems, but at the cost of removing some of the formatting from the book. That approach should be used only as a last resort for books that do not convert otherwise. Not converting to KFX at all may yield better results for those books.

My post on ExtractCoverThumbs was meant for the the specific user that I replied to. It is possible to combine the various pieces called out in that post to produce a test version of ExtractCoverThumbs that supports KFX, but that change has not been vetted by creator of that program and there may be flaws. Also, ExtractCoverThumbs is a stand-alone program, not a calibre plugin. It requires use of Python.
For now, if you want your KFX book to have a cover thumbnail on an e-ink kindle then you should set the "amazon" identifier of the book in calibre to the 10-character ASIN of an equivalent book sold by Amazon (if such exists.) Here are instructions for doing this:
- Search amazon.com with a web browser for an Amazon equivalent of the book you are converting and bring up its page. The web browser address bar will have something like "https://www.amazon.com/gp/product/B005MZN2B2/...". The ASIN (Amazon Standard Identification Number) for the book is the 10-character string that begins with a "B".
- In calibre select your book, choose "Edit Metadata", and in the "Ids:" field add "amazon:B005MZN2B2" (without the quotes and using the ASIN you discovered). If there is something already in the "Ids:" field then separate the new information with a comma.
- Convert the book to KFX and sideload it to your kindle device. It should show the cover thumbnail of the book you found previously on Amazon.

I agree that it would be nice if calibre supported KFX sideloading and thumbnail creation. I am not interested in working on that at the moment myself.

That is probably true. I have no interest in X-ray and have not investigated how it might work with KFX.
