GrapheneOS I don't think the fold variants are higher end. The screens looks incredibly dated, even the inside one. You can clearly see pixels and the cover display doesn't even have ltpo, so you won't use AOD. It's extremely heavy as well.
The Pro variants are better in every way except that they can't fold open.
I don't say the folds are bad, I have one myself and quite like it, but you have to decide between actually good hardware or the option for a big screen. The Pros have literally no negative sides IMHO, while the fold is clearly limited. But that is exactly fine if you want that 8" screen in your pocket.
