I am actually producing PDF/X-4 print-ready stuff with Inkscape, ghostscript and Scribus. I even have TrimBoxes and proper CMYK.
But it involves many manual steps, especially overprinting for the K color channel does not work and I need to adjust every polygon and vectorized text manually.
I whish it would be possible all in one tool. I can afford the time, because it is only a hobby. If it would be professional the extra steps involved make it not good enough.
ghostcript can add a color profile, too. I use the regular ISO coated v2 (without the 300%). This is just a step to not do all things in Scribus by hand and make sure colors are not out of gamut.
I don’t now the command line from the top of my head. Just ping me again, so when I am on my computer I can send the complete ghostscript cli line that currently works for me.
The final profile is set up by Scribus, where I have set it to the ISO coated with 300%. Ideally I would like to have less steps in the chain, so that a change in the Inkscape-source involves less manually steps. One can dream of it. (:
I don’t now which of ProcessColorModel or ColorConversionStrategy is the important one. I kept both and did not bother to try to omit one of them. -dPDFSETTINGS=/prepress makes sure that embedded bitmaps are in 300dpi and I think -f prevents Ghostscript staying in interactive mode after all pages have been finished.

I use Ghostscript for postprocessing the PDF files. What do yo I use to add a color profile for example?

Here I am again.
I’ve been fantasizing of making a simple GS GUI.
Finally I found the time to write down, how I use Ghostscript:
gs \ -sDEVICE=pdfwrite \ -o /output/gs_file.pdf \ -dPDFSETTINGS=/prepress \ -sProcessColorModel=DeviceCMYK \ -sDefaultCMYKProfile=/path/to/ISOcoated_v2_eci.icc \ -sColorConversionStrategy=CMYK \ source/file.pdf \ -fI don’t now which of
