The default beamer font seems to be Computer Modern sans serif. How do I change this to serif?
Note: \setbeamerfont{<element>}{family=\rm} seems to work for specific elements such as title, but I want this to be a global change.

If I understand your question correctly, you are trying to get a document typeset using a sans-serif font rather than the "ordinary" serif font. In addition, you want the font that's used in math to be upright rather than "slanted". The only math font I'm familiar with that's upright rather than slanted is the so-called "Euler" font; it goes reasonably well with Computer Modern fonts, both serif and sans-serif. If the Euler font suits your needs, you should add the following commands to the preamble of your document:
\renewcommand{\encodingdefault}{T1}
\usepackage[T1]{fontenc}
\renewcommand{\familydefault}{\sfdefault}
\usepackage{eulervm}
The following example using \mathrm seems to work nicely in MikTeX 2.9 with a tikz-box:
\documentclass{article}
\usepackage{lipsum}
\usepackage{tikz}
\newcommand*{\mycolorbox}[1]{
\begin{tikzpicture}
\node[rectangle,inner xsep=10pt,inner ysep=10pt,
anchor=south,text width=\columnwidth,shade]{#1};
\end{tikzpicture}
}
\renewcommand{\familydefault}{\sfdefault}
\usepackage{helvet}
\usepackage[mathrmOrig]{sfmath}
\begin{document}
sans serif text
\mycolorbox{Sans serif: $a + b$, CM: {$\mathrm{c}$}}
\end{document}
I think you need to explicitly enable this with the mathrmOrig option in sfmath. The result looks like this:

You can put the following in your preamble:
There are some options to this command. They are described in ยง18.1 of the
beamermanual.
