A plain ext4 with the 'discard' mount option will do just fine.

It's possible to do, but it is not needed that much.
If you're trying to conserve drive's resources - just write less on it.
I.e. redirecting .xsession-errors to /dev/null, removing that annoying
/var/log/journal directory, adding a good set of filters to rsyslog,
etc.

For instance, this low-cost SSD that I use in my laptop endured about
1.8 Tb writes over 3.5 year usage, and shows no signs of degradation.

They do not do it, because to F2FS is designed to operate over raw NAND
chips, not typical SATA/NVMe controller. In layman terms, F2FS is
something that's suitable for your phone, or your router, but not your
PC.
So again, it's possible to do, but again, it's not really needed.
