Answer 1

I think you'll have to use finish option to draw a node like the title over the text.

Look at section "9.4 drawing scheme" in tcolorbox documentation to see in which order are all box elements drawn. The text is always the last one, even over overlays. The only option is finish code (section 10.9).

\documentclass{article}
\usepackage[most]{tcolorbox}
\usepackage{lipsum}
\begin{document}
\begin{tcolorbox}[enhanced,skin=enhanced jigsaw,attach boxed title to bottom center,title=Hello,
attach boxed title to bottom center={yshift=\tcboxedtitleheight},
finish={\node[draw=red, rounded corners, fill=red!30, anchor=south, minimum size=2cm] at (frame.south) {Hello};}]
  \lipsum[4]
\end{tcolorbox}
\end{document}
