Is there a service that you can pay upfront to keep your domain/mail/documents/whatever kept alive forever? Something like cryogenics but for data.

In some states of the US there are Laws connected to UFADAA or RUFADAA, see (only as an example):

From what I understand, the "best" (and probably the only sensible/effective way) is to transfer your "digital assets" to some form of trust, not really easy or affordable by many.
So no. Once you stop fighting and constantly pressing your vendor/supplier they'd simply take your money and not provide you any service.
This will happen way before you croak btw. By the time you are 70 people will be ripping you off left and right.
