In your example, the caption is limited to image width.
What I want is something as
\setupcaption[figure][width=\textwidth, align=middle]
does. But long texts should behave as document text (hyphenated, including).
Thanks by attention.

How about this:
\starttext
\placefigure[here]{This is just an example for this is just an example for this is just an example for this is just an example for this is just an example for this is just an example for this}{\externalfigure[any][width=0.5\textwidth]}
\stoptext
