(1) Write a program controlling any capable text processing software's
programming interface, as was suggested.  This method will be
forgetful of internal data formats of these programs.  The method is
unavailable if you don't have the programs.  A third party could be
offering a ready made class library for generating the files, though.

(2) Depending on the level of abstraction, one may generate .gen
files or maker files just like LaTeX files.  I find targeting
anything at a level lower than that to be an attempt at reinventing
big wheels.

Really? I don't know how the Fortran people had generated input
for TeX.

Nearly?

Have your Ada program generate a TeXmacs files, in Scheme format.
Then,

$ texmacs --convert test.scm test.pdf --quit

Similar to how one uses LaTeX or Lout.
Is it possible to run Word simply like

C:\MyFiles> word /convert /in:test.docx /out:test.pdf  /quit

\special is indicating a need for output that TeX alone cannot
produce.  Is this standard enough?

I got carried away, thinking about the document generating processes,
and in particular, about how a document will be used.  (By clients,
programmers, ISO, ...)
If you want typographically flexible typesetting (really, layout),
TeX is out of the question (for example, frames that span a page
break?).  If you wanted to write an Ada program that generates this
in PDF directly, wouldn't you be trying hard to reinvent text
formatting?
