I chose checkpoint_smoothing because it tells you what the parameter is
for. If you want more smoothing, tune it up, and if you want less, tune
it down. checkpoint_fraction makes you wonder what you can do with it
and why you would change it.

No, I chose _smoothing on my own. People didn't like
checkpoint_write_percent either (including).
