I love beamerboxesrounded boxes in Beamer presentations, but the text fits too tightly into the box. So I would like to use equal but wider and higher margins (left, right, top, bottom) around the text, or padding inside the box. How is it possible?

The empheq package is your friend. The wide box is made with a normal box, with some space left and right, that you can adjust to your likings.
\documentclass[11pt]{article}
\usepackage{empheq}
\newcommand*\widefbox[1]{\fbox{\hspace{2em}#1\hspace{2em}}}
\begin{document}
\begin{empheq}[box=\widefbox]{equation}
\bar{\nabla}^{\mu} \bar{h}_{\mu\nu} = 0
\end{empheq}
\begin{subequations}
\begin{empheq}[box=\widefbox]{align}
\bar{\nabla}^{\mu} \bar{h}_{\mu\nu} & = 0 \\
\bar{\nabla}^{\mu} \bar{h}_{\mu\nu} & = 0
\end{empheq}
\end{subequations}
\end{document}

Upon my EDIT, I still don't have a clue what I am doing, but I did manage to get things into beamer. The use of physical dimensions, notably 4.2in for the \makebox and 4.65in for the \tcbox width, are given in physical dimensions because I don't know what the corresponding variable names are for beamer margin widths, etc. They may, therefore need changing depending on your beamer template.
\documentclass{beamer}
\usepackage{tcolorbox,lipsum}
\tcbuselibrary{skins}
\begin{document}
\begin{frame}
\raisebox{4cm}{\makebox[4.2in]{
\tcbox[enhanced, boxrule=0pt, arc=0pt, width=4.65in, top=.2in,bottom=.3in,
interior style={left color=gray!05,right color=gray!50}]
{\begin{minipage}{4.65in}
\lipsum[1]
\end{minipage}
}}}
\end{frame}
\end{document}
