Pity about that C-41 exception---it's one of the reasons I don't shoot it much. I think I remember, though, PE saying that the longevity of modern C-41 materials was enormously improved; not to Kodachrome levels or anything, but enough to make a meaningful difference in terms of the transgenerational shoebox.

Agreed. The archival quality of film can be quite remarkable and to me is a nice "feature".

IIRC, Color negs have less longevity compared to E6 materials but is the difference quite pronounced? I recall a pnet discussion about it and Ron Andrews quoted more stability on E6 compared to C41. Something about different couplers mentioned.
RA4 paper is quoted between half a century to 200 years. There is still a huge volume of it used by photofinishing, perhaps will slowly improve is R&D is put on it.
Well processed B&W on Polyester base seems the ultimate thing, together with proper FB.

All will depend on storage, added to processing. Hot and Humid and it will be sooner gone.

As of digital I too don't trust it. I lost a couple of folders (probably misplaced) and mistrust it. Operator error but I am much more careful with the physical archiving way.
