Film decays easily. I've been behind the scenes at a film storage museum. Fascinating.

OTOH nobody really knows how long the data in an optical device really lasts (like CDs, DVDs, BRs).

But even the read-only must have been written to once.

Unfortunately the longest lasting material is also the most flammable

That's one reason why storage is so complex.

In essence it is pressed smokeless gunpoweder (nitrocellulose = gun cotton)

I hope my box of family photos does not explode.

Films and photos tend to use different materials.

Mostly they are negatives.

Silver plates, glass plates or already (semi)synthetic polymer strips?

I have glass-mastered, mass-production CDs from 1990 - 1992 that are decomposed beyond use already.

Out of curiosity I got out one of the first CDs I purchased in the late 80s or early 90s (a version of R. Strauss' Don Juan recorded in 1979, and going by the disc you would think it was pressed that year, which I doubt) and it still plays without issues.

I think CDs vary enormously in this respect.

polymer strips (probably, I have no idea, they are not plate)

Last _{well, if it won't play on a CD player, it won't rip onto a computer, and you can see right through bits of it, I reckon I've spotted it} post.

I find great differences between CD players too. I have to keep in mind sometimes which CD to put into which player.
