Yes Zwilling, how I could I miss out some of your recommendations!
I agree with all except 電車（青）, sakura trees and D51きしゃ（青）.
電車（青）is only a consideration, but not the rarest in the range. There are a few survivors today, look it up and you will see that some of them still have their boxes... with that colour code sticker intact heheh...
Sakura trees again is another consideration. They were never sold on their own, but they were included in the 牧場セット (I don't know if other sets that have the trees or whether a single item actually exists). Actually I have no idea how many survives today but I have a few contacts that own them. I agree that there are few in existence.
D51きしゃ（青）, turns out to be less than 70 units the last time I checked every auction and social media. I went to the deep web to search, and I found 6 more from the dead blogs. It is an exceptional rare thing, but not even a consideration of the rarest.
By the way, regarding the メロディーD51セット, I went to Fuji-san's house that day and he has that set. The melody is unknown as the electronics are dysfunctional.
Also I wish to add the 1979 自動ポイントセット as one of the rarest. Plain modified basic set layout but there are only 2 surviving boxes in the world as of today. I'm actually surprised that it is rarer than some of the 60s Plarail.
