The bad news is that I couldn't figure a way to do this purely within a STY 
file. The good news is that only a slight modification (backward compatible)
to LaTeX is needed to accomplish our goal.

A comment: The poster correctly chooses to continue to use the same markup 
for the caption no matter whether it lies within a figure or table.
This is a choice in favor of descriptive markup---the correct choice IMHO.

************* cut here---beginning of Bruggink.sty **********
% Bruggink.sty---provide for independent formatting for float captions.
% The following is a re-definition of the \@caption macro which lets
% you format your figure captions differently from your table captions, etc.
% Your .sty file must provide for a meaning for, e.g., \@makefigurecaption, 
% etc.  If you do not, the default \@makecaption will be used.
\long\def\@caption#1[#2]#3{\par\addcontentsline{\csname
  ext@#1\endcsname}{#1}{\protect\numberline{\csname
  the#1\endcsname}{\ignorespaces #2}}\begingroup
    \@parboxrestore
    \normalsize
    \expandafter\let\expandafter\@tempa\csname @make#1caption\endcsname
    \ifx\@tempa\relax\let\@tempa\@makecaption\fi
    \@tempa{\csname fnum@#1\endcsname}{\ignorespaces #3}\par
  \endgroup}
%
% Here is the content of a .sty file containing definitions using the above
hook.
%
% The following is the same as the \@makecaption in book.sty:
\long\def\@makefigurecaption#1#2{%
 \vskip 10pt 
 \setbox\@tempboxa\hbox{#1: #2}%
 \ifdim \wd\@tempboxa >\hsize #1: #2\par \else \hbox
to\hsize{\hfil\box\@tempboxa\hfil}% 
 \fi}
%
% The following is slightly different from the \@makecaption in book.sty:
\long\def\@maketablecaption#1#2{%
 \vskip 10pt 
 \setbox\@tempboxa\hbox{#1. #2}%
 \ifdim \wd\@tempboxa >\hsize #1. #2\par \else \hbox
to\hsize{\hfil\box\@tempboxa\hfil} %
 \fi}
************* cut here---end of Bruggink.sty **********

And here is a document instance to test the above .sty. Note that this .sty
is tested here with book.sty; it should work equally well with article.sty

************* cut here---beginning of Bruggink.tex **********
% Bruggink.tex---illustrate how to use Bruggink.sty
\documentstyle{book}
\documentstyle{bruggink}
\begin{document}

\begin{figure}[h]
Content of figure
\caption{Figure caption}%
\end{figure}

\begin{table}[h]
Content of table
\caption{Table caption}%
\end{table}

\end{document}
