Page-wide figure with sidecaption in two column article

Question

Having some trouble getting my latex document to format this properly. I know there's difficulty using floats in two column documents, but there's got to be a way to make this work properly. I'd like to have an (almost) page-width figure placed on the bottom of a page that is two-column formatted for text, while also being able to place the caption on the side of the figure.

I've tried a variety of packages including sidecap, dblfloatfix, and stfloats, and I'm sure there's a way to do it, I just can't figure it out. Thanks for any help!

Example:

Here's my MnWE. Had to create a dummy document:

\documentclass[twocolumn,superscriptaddress,floatfix,longbibliography]{article}

\usepackage{geometry}
\geometry{margin=1in}

\usepackage[backend=biber, style=chem-acs]{biblatex}

\addbibresource{references.bib}

\usepackage{mathptmx}
\usepackage{amsmath,amssymb} % math symbols
\usepackage{bm} % bold math font
\usepackage{graphicx} % for figures
\usepackage{comment} % allows block comments
\usepackage{textcomp}
\usepackage{float}
\usepackage{array}
\usepackage{siunitx}
\usepackage{booktabs}
\usepackage{textgreek}
\usepackage[dvipsnames]{xcolor}
% \usepackage{parskip}
\usepackage[version=4]{mhchem}
\usepackage{xstring}
\usepackage{xspace}

\usepackage{titling}

% \usepackage{stfloats}
\usepackage{sidecap}
\usepackage{dblfloatfix}

\usepackage{titlesec}
\titleformat*{\section}{\normalfont \bfseries}
\titleformat*{\subsection}{\normalfont}
\titleformat*{\subsubsection}{\normalfont \itshape}
\usepackage{enumitem}
\setlist{leftmargin=*,topsep=1pt,parsep=0pt}
\usepackage{xcolor}
\usepackage{hyperref}

\begin{document}
\section{\label{sec:introduction}Introduction}

Answer 1

See if the following is what you looking for:

\documentclass[twocolumn]{article}

\usepackage[margin=1in]{geometry}
\usepackage{lipsum}

\usepackage{graphicx} % for figures
\usepackage{sidecap}

\begin{document}
\section{Introduction}
\label{sec:introduction}

\lipsum
\begin{SCfigure*}[0.25] % <---
\begin{wide}            % <--- defined in "sidecap" package
     \includegraphics[width=0.75\textwidth]{example-image-b}
    \caption{\lipsum[66]}
    \label{fig:cat}
\end{wide}
\end{SCfigure*}

\lipsum
\end{document}
