I have a small nitpicking query
I have:
$S\sqsubset\mathbf{P}$
and noticed that the \sqsubset symbol is a bit too low (off centered) for my liking. Is it possible to shift it up slightly?

You can us bm to access the bold + from the font used for \boldmath (which in the standard setup is the font used for \bfseries in text.
\documentclass{article}
\usepackage{bm}
\begin{document}
\showoutput
$1 + 2 \bm{+} 3$
\end{document}
Rather than raise the height of \max_{r_t}, I would lower the \mathbb{E} particle, making it look more like a purely symbolic entity (rather than an uppercase letter). One way to do this is to encase it in a \vcenter{\hbox{...}} set of directives.
Note that this method (as well as the one you initially proposed) "works", typographically speaking, only if there's a large symbol (such as \sum and \int) nearby. If the surrounding material is mostly text aligned on a common baseline, lowering the particle \mathbb{E} would probably look bizarre.
Incidentally, I would not use \left and \right to size the fence symbols in this formula, as doing so results in fences that are too large and thus dominate the material they enclose. Instead of \left and \right, I would use \biggl and \biggr, striking a balance between the material enclosed by the fences and the fences themselves.
\documentclass[14pt]{beamer}
\usetheme{Madrid}
\begin{document}
\begin{frame}
\[
\max_{r_t} \biggl\{
\mathbb{E}
\biggl[ \, \sum_{t=0}^{\infty} r_t^t \biggr]
\biggr\}
\quad\text{vs.}\quad
\max_{r_t} \biggl\{
\vcenter{\hbox{$\mathbb{E}$}}
\biggl[ \, \sum_{t=0}^{\infty} r_t^t \biggr]
\biggr\}
\]
\end{frame}
\end{document}

You can redefine
\sqsubsetto take an optional argument that would raise it:The updated
\sqsubsetis set as a binary relation\mathrel. Note that if you want to use square brackets after\sqsubset, you need to surround it with braces. The new usage is\sqsubset[<len>]where<len>is any recognized (La)TeX length.
