It does not affect whispersync, but it does indirectly affect the availability of the book covers. There was a recent discussion on this topic, it's a good read:

Basically, if you consider those three things:
- Syncing of last page read across devices
- Book covers
- Advanced text formatting
Unless your Kindle is still on a fairly old version of the firmware (i.e. lower than 5.8.5), it is not possible to have all three. You can have:
- 1 and 2 (but not 3) by using the "Old" MOBI format
- 1 and 3 (but not 2) by using "Both" as the MOBI format, or converting to AZW3
- 2 and 3 (but not 1) by sideloading your books via USB
So the answer to your question:

Maybe with a certain name? In a certain location on the Kindle (because on the Android the cover shows no problem)? Or a certain image size?

is unfortunately no.

Or is there benefit of "New", as long as the device is not too outdated for that option (and if so, how do I know that?)

Indeed when using "Both" you get a file that contains two versions of the book, one in the old MOBI format, and one in AZW3. When you send the file to amazon, their servers keep both versions. If you request your book from an older Kindle, then you will get the MOBI version, because those kindles don't support AZW3. If your Kindle does support it, then the AZW3 version will be downloaded to your Kindle.
As far as I know there is no "New" option, because "New" would be a plain AZW3 file, so you would convert directly to AZW3 in Calibre instead.
