I've read anecdotal numbers as low as 5 years, and marketing claims are always huge (100 years!), but most of what I see is about the lifespan is when the flash is actively used (so running out of read/write cycles), rather than the on-the-shelf lifespan of already written data.

I'd suggest assuming some periodic read-only use, since we *should* be
testing our backups regularly to discover decay *before* it makes
something irretrievable.
