I believe MXF closed captions work similarly to Transport Stream CC
content: Closed Caption is separated from video, and is present in a
different track.

I don't have a sample here, but according to this post
<https://ffmpeg.zeranoe.com/forum/viewtopic.php?t=2406>, CC appears as a
SMPTE 436M data track in MXF content.

Aside from that, this page from Intel
that describes a procedure, along with the code needed, to insert and
display CC for H.264 using SEI messages; or MPEG-2 with user data.
