Bold number in siunitx column with SF font

Question

I would like to achieve exactly the same thing that was questioned and answered here but with SF font.

This works:

\documentclass[11pt]{standalone}
\usepackage{siunitx}
   \sisetup{detect-weight,
            table-format=2.2}
\usepackage{etoolbox}

\DeclareFontSeriesDefault[rm]{bf}{b}
\newcommand\B{\bfseries}

\begin{document}
abc \textbf{ab}
\begin{tabular}{ |S[mode=text] | S |}
   12.34   &   12.34   \\
\B  12.34   &\B 12.34   \\
\end{tabular}
\end{document}

But with

\renewcommand{\familydefault}{\sfdefault}

it does not (it uses extended bold, so the numbers are not aligned)

I tried changing

\DeclareFontSeriesDefault[rm]{bf}{b}

to

\DeclareFontSeriesDefault[sf]{bf}{b}

with no success.

Answer 1

The command

\DeclareFontSeriesDefault[sf]{bf}{b}

would probably work, but unfortunately as this post stated neither Computer Modern nor Latin Modern supports bold (not extended) in their Sans Serif variant.
