I don't know if I get you right, but I think you are talking about
the width of the caption. It adaptes to the with of the figure.
There is the “minwidth” parameter for \setupcaptions, but since the
short captions will not be centred it's probably not what you aim
for. I don't have a solution, but a workaround that alters the
global width setting for an individual caption:
\useMPlibrary [dum]
\starttext
\startplacefigure [title=Foo Bar]
\externalfigure [placeholder]
\stopplacefigure
\setupcaptions [width=.8\textwidth]
\startplacefigure [title={\input tufte\par}]
\externalfigure [placeholder]
\stopplacefigure
\setupcaptions [width=fit]
\startplacefigure [title=Foo Bar]
\externalfigure [placeholder]
\stopplacefigure
\input knuth
\stoptext
