The idiomatic way to label

LaTeX

\section{Section}\label{blah}

Section~\ref{blah} % Section~1

Page~\pageref{blah} % Page~X

% (context dependent)
\cref{blah} % Section~1

Calling \label{name} associates name with the value of the last-incremented LaTeX counter, and the location in the document. \ref{blah} returns the value associated with name, optionally with a hyperlink to the associated location in the PDF. \pageref{blah} returns the page number for the associated location. \cref{blah}, based on \usepackage{cleveref}, hooks \ref to also record the kind of the last-incremented counter and exploits that to return a string fully identifying the label (and a hyperlink). cleveref also supports passing multiple references in, and automatically sorting them into a nice-looking setup.

TODO autoref, varioref? They seem like subsets of cleveref.
