To save SSD life, I moved swap to a swap-file on a md0 non-ssd part

It is probably better to have a lot of RAM, so that swap is not used
that often, and move swap back to SSD as difference in access speed is
rather dramatic; you don't have movable parts that need repositioning
and pure transfer speed is few times higher.

Of course if you use hibernation that will tax swap space, but when one
is worn out, after say 2000 writes, you can use different part of the
disk that wasn't used that much and repeat that as long as remain disk
capacity is sufficient for your needs.

The lifetime of a drive is different from individual memory cell
endurance as built in controller will stop using bad block, just the
same way it happens with classic, mechanical, drives. How far this can
go depends on a size of memory that is allocated to hold index of bad
blocks.
