I do agree that I still have a need for some tonal adjustment after
using filmic (which is now my default path). The lack of highlight
detail/contrast ... most often in the sky or snow texture .... is where
I have the greatest difficulty. I still resort to using the
highlight-shadows module despite severe artifact problems.
For my taste, I also find that images need added saturation after
filmic. I do find that adding the middle-tone-saturation (under the
'look' tab) is very helpful and solves most problems .... generally I
stay away from velvia.

This is just a comment on the filmic module. I like it actually over the
base curve but I still find the need to adjust certain tones,
emphasizing them with the tone curve. I don't think that will change.
The filmic adjustments are often too coarse.
Also, for some reason, compared to using darktable 2.4 a long time ago
with base curve/tone curve, after using filmic in darktable 3 my images
seem to be quite desaturated. I usually activate velvia and tweak
colours either using saturation or color zones to generate something
that I would consider more accurate.
I probbaly am not using the most efficient workflow, but actually I am
quite fast at darktable having used it for 5 years as by first Raw
developer, but I was just wondering if other people are using a
different workflow when it comes to improving saturation after using filmic.

After you have read the replies to your initial question, I am sure that
you must be quite confused. Let me try to more correctly find an answer
that may make sense.
There are two possible development 'routes' in darktable. 1.) uses the
'base curve'; 2.) uses the 'filmic-rgb' module.
If you use the base-curve approach .. this module designed to
approximate a camera jpg and is not normally modified by the uses. If
you wish to modify the effects of the base-curve then you should be
using the tone-curve to make corrections as needed.
Patrick has been advocating that you use the filmic-rgb approach (a more
recent darktable development); in which case the base-curve should be
switched off totally and then all/most of the adjustment will be done
within filmic-rgb.
I would strongly recommend that you familiarize these processes through
the excellent manual or the numerous videos that are available on-line.

I use Darktable 3.0.2 (the latest version as far as I know).
I have read about the base curve module in the user manual. I understand the
mechanics about changing the curve, but the whole concept is very abstract
to me.

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?

you don't say what version dt you employe but a better approach would be
to enable filmic and follow:
https://discuss.pixls.us/t/darktable-3-0-for-dummies-in-3-modules/15849
as advised in this thread.
about base curve:
https://www.darktable.org/usermanual/en/modules.html
3.4.1.4.Base curve
fwiw, I have filmic enabled.
aiui, base curve matched exactly to your camera/model is an effort to display
a basically acceptable jpg image "resembling" but not matching your
"basic" ooc image. imnsho, you would be better served employing filmic
and disabling base curve.
