Complicated even more by our reliance today on proofing and developing on monitors (RGB) and then printing to ink / paper (CMYK).
My workflow (just what I do, not saying it is right) is to work in Prophoto colorspace for post processing in Lightroom and / or Photoshop. Printing locally is done from Lightroom with printer profiles that match the paper used. But anything sent out to another lab is exported as sRGB unless they request otherwise. It is important to know what the lab uses internally, (almost always sRGB) so you can best match what they are going to use. If you are going to use a particular lab often it is worthwhile finding out what setting sthey recommend and making an export preset that matches those. At least in LR, I assume Darktable has a similar function.

If you are printing in house you should obtain the printer profiles for that printer and the paper you will be using. LR gives you the ability to softproof using that profile to make a reasonable showing on screen of what it will look like on paper.
