Hi
You write that as a parent you have very little time to spend on editing photos, and you like Capture One because it lets you edit photos fast. As a parent of a small child that requires lot of care, I know exactly what you mean. That is why I invested quite some time in streamlining my photo editing in Darktable.
I wrote an post about my workflow here: Darktable speedrun: Stylish edits in 40 seconds
As a matter of fact, I’ve gotten so fast at getting acceptable result, that its getting a bit boring. I took this photo an hour ago. It only took me 57 seconds to edit this photo. And without any stress or haste.
