I suspect that you need to get your matches contained in various groups. For

This mostly did the trick. It now works in some cases but not everywhere, see
the minimal example below.

You didn't provide any examples, so the above is a guess.

You are right, this is a MWE

   \documentclass[a4paper]{article}
   \begin{document}
      SUT (SUT) [SUT] {SUT} SUT,
      $SUT$
      \section{A section about SUT.}
      \begin{itemize}
         \item SUT
      \end{itemize}
      \begin{figure}\caption{whatever SUT is}\end{figure}

      ftp://erlang.org/doc/man/erl_tracer.html
      \url{ftp://erlang.org/doc/man/erl_tracer.html}
   \end{document}

in this case, the acronym SUT and the URL are correctly ignored in paragraphs
(also when followed by punctuation symbols) but not when in a command as
\section, \url or \caption. What I see is in the attached pic.

Currently, my .vim/after/syntax/tex.vim contains:

  syn cluster texFoldGroup add=UrlNoSpell,AcronymNoSpell
  syn match UrlNoSpell '\w\+:\/\/[^[:space:]]\+' contains=@NoSpell
  syn match AcronymNoSpell '\<\(\u\|\d\)\{3,}s\?\>' contains=@NoSpell

Probably, there will be another group to add these patterns. Where can I read
all the possible groups?

Well, all the groups are explicitly laid out in syntax/tex.vim, albeit embedded with the rest of the syntax highlighting. What you might consider doing is using hilinks.vim (http://www.drchip.org/astronaut/vim/index.html#HILINKS, :HLT!) which will then tell you what syntax and highlighting is currently in-use under your cursor. Using your example I typed :HLT!, placed the cursor on the f in ftp:... and noted that the syntax stack has texDocZone->texSectionZone -- so you'll want to use

syn cluster texSectionZone add=UrlNoSpell,AcronymNoSpell

to your after/syntax/tex.vim file.
