I think you are chasing Unicorns here.

SD cards and thumb drives are designed as limited usage cheap storage,
and no amount of faffing around with filesystems is going to change
that. At some stage no matter what file system is in operation data
needs to be (over) written and blocks need to be erased to do it.

You can buy high-endurance devices, aimed at industrial use cases,
dashcams, etc, if you’re prepared to pay for them.

Professional level SSDs are designed to adapt the writes to extract
the best out of a limited block erase life, and that's that, and you
pay for that by using a more conservative memory cell design and
hanging a lot of smarts in front of it.

Since there is no 1:1 correlation between the sector you think you are
writing to, and the actual physical RAM on even a thumbdrive, there is
nothing you can do at the operating system level other than caching
your writes and doing them in single big chunks in the hope that some
of them end up in the same erase page, and using the DISCARD function.

For cheap devices agreed. Keep spare in stock, you’ll probably need it.
