Don't know what versions of Ember and Kodi/Xmbc you coming from but your naming scheme is old and legacy. Ember use the same as Kodi and it's been like this since the Frodo version come out.

For the actor thumbs, you don't need to download every picture, you can have an URL inside the nfo and both Ember and Kodi will use that

If you get Ember to recognise your current naming scheme you can let Ember rewrite everything for you to the new standard, you don't have to do it manually

What part of my naming scheme is old exactly, because it still works perfectly fine in Kodi v16.1 from what I can see.
I assume you just mean movie.tbn should be renamed to poster.jpg? If ember can re-write movie.tbn to poster.jpg, then that would be awesome and I'll look into it shortly

You are also correct, I forgot that the actor images are stored as a URL in the NFO file, so I'm glad I use 'expert' settings in Ember (as shown as komplex screenshots) and just turn it off (yes I know I don't need to use expert mode to do that, but it is on by default, which imo it shouldn't be).

I also definitely prefer "poster.jpg" and "fanart.jpg" compared to the default Filename-poster and Filename-fanart which usually ends up as a fairly long file name. Surely that is not legacy by using poster.jpg instead of filename-poster,jpg?

Yes Kodi supports it but it's still legacy and one day it may be removed, check the wiki for reference
I think the long name came for people that had all movies in one big folder (no separate ones) so a poster.jpg doesn't work in that use case
