Indeed, there is no simple way to achieve what you want and textcommand
is the easiest solution (but i would include the strut in the command), e.g.


<example id="1">
\unprotected\long\def\putcompletecaption#1#2%
  {\doifsomething{\floatcaptionparameter\c!spacebefore}{\blank[\floatcaptionparameter\c!spacebefore]}%
% \floatcaptionparameter\c!before % test for side effects first
   \noindent
   \xdef\lastcaptiontag{\strut#1}%
   \dostartattributes{\??kj\currentfloat}\c!style\c!color\empty
     \ifnofloatnumber
     \else
       \hbox{\doattributes{\??kj\currentfloat}\c!headstyle\c!headcolor{\strut#1}}%
       \ifnofloatcaption \else \ifemptyfloatcaption \else
         \doifelsenothing{\floatcaptionparameter\c!spaceinbetween}
           {\scratchskip\floatcaptionparameter\c!distance\relax
            \dotfskip\scratchskip\emergencystretch.5\scratchskip}
           {\blank[\floatcaptionparameter\c!spaceinbetween]}%
       \fi \fi
     \fi
     \ifnofloatcaption
       \globallet\lastcaptionht\!!zeropoint
       \globallet\lastcaptiondp\!!zeropoint
     \else
       \doattributes{\??kj\currentfloat}\c!textstyle\c!textcolor
         {\xdef\lastcaptionht{\strutheight}%
          \xdef\lastcaptiondp{\strutdepth}%
%        \begstrut#2\endstrut\endgraf}%
         \floatcaptionparameter\c!textcommand{\begstrut#2\endstrut}%
         \endgraf}%
     \fi
   \dostopattributes
% \floatcaptionparameter\c!after % test for side effects first
   \doifsomething{\floatcaptionparameter\c!spaceafter}{\blank[\floatcaptionparameter\c!spaceafter]}}

\starttext

This is some text with a reference to a table named \about[tab:table].

\placetable[here][tab:table]{My caption.}{...}

\setupcaptions[textcommand=\groupedcommand{}{.}]

This is some text with a reference to a table named \about[tab:other-table].

\placetable[here][tab:other-table]{My caption}{...}

\stoptext
</example>


but it’s possible to get the desired result also with a selector, e.g.


<example id="2">
\defineselector[caption][max=2,n=2]

\startsetups select:caption
\setupselector[caption][n=1]
\stopsetups

\setupcaptions[setups=select:caption]

\starttext

This is some text with a reference to a table named \about[tab:table].

\placetable[here][tab:table]{\select{caption}{My caption.}{My caption}}{...}

\stoptext
</example>
