I also struggled get a PDF/A with pdfLaTeX and pdfx, and it did not
work out in the end.
I changed to a different route - and I am nearly there now - where I
use hyperxmp, which is nice to use and which also supports LuaTeX.
Color profile inclusion (there's a small bug in the original pdfx
code) and glyph management are taken from pdfx. I think these should
work in LuaTeX, too. The code, in the end, is very compact, as
hyperxmp provides higher-level access to metadata writing. It requires
modifications in the package source to write the PDF/A compliancy tag
and other things, but I am in contact with the author to include it.

True, I also spent a week. In the end, I found a combination I am
quite happy with: pdf-tools online validator  and Apache pdfbox
preflight . I did not find the later very much used by other
people, but it is very powerful and sensitive to issues. To be really
useful, also there I needed to modify the code to include the byte
offset, etc, to error messages .
There is maybe one more iteration for the LaTeX code, then I can
supply it if you are interested.
