I have enabled the base curve with preset "sony alpha like" (since I
have Sony cameras), and that is better than without.
But I have a hard time understanding how to manually edit the base
curve in a useful way. I can edit it, and I see how the image changes,
but it feels quite random to me. I don't know what to do to get the
result I want.
Most of the presets are for specific camera makers, so it's hard to
know which one to chose. Does it even make sense to use a preset for
another camera than the one taking the photo?

This is about basecurves:
https://www.darktable.org/2013/10/about-basecurves/
In short: base-curves have been created by comparing a RAW with a JPEG
_from a given camera model_ .
So this is kind of reverse-engineered, what the camera manufacturer
defines as "a good image" - and because of this and each manufacturer
has it's own opinion (based on what their marketing tells them) of what
"a good image" has to look like - there are many of them.
None of these is the absolute truth. They are just interpretations of
the truth.
You may use a base curve as a starting point but this module is not
meant to do adjustments to images individually.
You may use exposure and e. g. levels or tone curve to work on the
pictures individually.
