Expired film trove - shooting and dev tips or test requests

[Yobo57]

Hello I recently picked up a bunch of expired film from the 70s through 2000s that was destined for the trash, most likely never cold stored.
I’m looking to shoot most of it, any advice on exposing/dev?

For old color film, would it be better to cross process as black white? Also is the 1 stop per decade a fairly ok rule for color?

For the BW film should I shoot everything more or less box speed and dev as normal?

There is also a roll of Ektachrome Infrared from the 70s, E4 process. Would E6 dev work or would c41 be better? Also what speed would be best, anyone have experience with this film?

If anyone also wants me to try any specific tests with exposure or development on a particular film, here is the full list of stuff I can experiment with:

I’m campaigning for people who shoot black and white film to occasionally bracket a normal shot with another identical shot with two stops greater exposure. We can evaluate this “two stop” test after you develop the film.
