Minipage: Align text, image and caption

Question

I try to split my page into a text part on the left and an image on the right side. Therefore I use minipage and flushright.

There are 2 problems:

• I want to have the text and the image being top aligned. The minipage option [t] does not work unfortunately, neigther the try \vspace{0pt}.

• The image is right aligned properly, but the caption is not. It should be shifted to the right as well to be centered under the image again.

How can I achieve both? Thank you :)

MWE:

\documentclass{scrreprt}
\usepackage{caption}
\usepackage{mwe}

\begin{document}

\begin{minipage}{0.38\textwidth}
  \lipsum[2]
\end{minipage}
\begin{minipage}{0.57\textwidth}
  \begin{flushright}
    \includegraphics[height=10cm]{example-image-9x16}
    \captionof{figure}{Caption\\Long Caption}
  \end{flushright}
\end{minipage}

\end{document}

Probably the following gets closer to the desired output. (Lines indicate margins):

\documentclass{scrreprt}
\usepackage{caption}
\usepackage{graphicx}
\usepackage{showframe}
\usepackage{lipsum}
\usepackage[export]{adjustbox} %for the valign=t option
\begin{document}
\noindent
\begin{minipage}[t]{0.38\textwidth}
  \lipsum[2]
\end{minipage}
\hfill
\begin{minipage}[t]{5.7cm}
  \begin{flushright}
    \includegraphics[height=10cm, valign=t]{example-image-9x16}
    \captionof{figure}{Caption Long long Caption}
  \end{flushright}
\end{minipage}

\end{document}

Here is a version using measuredfigure from threeparttable:

\documentclass{scrreprt}
\usepackage{caption}
\usepackage{graphicx}
\usepackage{showframe}
\usepackage{lipsum}
\usepackage[export]{adjustbox} %for the valign=t option
\usepackage{threeparttable}
\begin{document}
\noindent
\begin{minipage}[t]{0.38\textwidth}
  \lipsum[2]
\end{minipage}
\hfill
\begin{minipage}[t]{0.57\textwidth}
\hfill
  \begin{measuredfigure}
    \includegraphics[height=10cm, valign=t]{example-image-9x16}
    \captionof{figure}{Caption Long long Caption}
  \end{measuredfigure}
\end{minipage}

\end{document}

Answer 2

paracol is a good choice.

\documentclass{scrreprt}
\usepackage{caption}
\usepackage{mwe}
\usepackage{paracol}

\begin{document}
\begin{paracol}{2}
  \lipsum[2]
  \switchcolumn
  \includegraphics[height=10cm]{example-image-9x16}
  \captionof{figure}{Caption\\Long Caption}
  \switchcolumn*
  \lipsum[3]
  \switchcolumn
  \includegraphics[height=5cm]{example-image-16x10}
  \captionof{figure}{Caption\\Long Caption}
\end{paracol}

\end{document}
