How to change text font to Helvetica for figure captions only

Question

I am writing a journal in LaTeX in IEEE format. When I make a figure captions it is the same font as the rest of the document (Times). However, I want all the figure captions to be of type Helvetica and of size 8pt.

\documentclass[journal]{IEEEtran}
\usepackage[utf8]{inputenc}
\usepackage{graphicx}
\title{Test}
\author{Me}
\date{June 2021}
\begin{document}
\renewcommand\thepage{10.\arabic{page}}
\maketitle
\section{Introduction}
\newpage
\section{page 1}
\newpage
\section{page 2}
\begin{figure}[h]
    \centering
    \includegraphics[width=5cm]{example-image-a}
    \caption{Caption}
    \label{fig:my_label}
\end{figure}
\end{document}

Is it possible to make all figure captions font Helvetica and size 8pt throughout the entire document, without changing the font and size of the main text?

I think this is the answer you are looking for: https://tex.stackexchange.com/a/455606/118712 Although it is not very clear from the answer phv defines Helvetica. This is explained very well here: https://tex.stackexchange.com/a/25251/118712 — Markus G., Jun 18 '21 at 12:16
In terms of font size: If your document uses 11pt as the default, then \small is per defintion 8pt. There is an excellent conversion table here: https://tex.stackexchange.com/a/24600/118712 — Markus G., Jun 18 '21 at 12:19
Does this answer your question? How do I specify a font for labelfont in caption? — Markus G., Jun 18 '21 at 12:25
@Bernhard You are right, my mistake. It is correct in the table I linked to. — Markus G., Jun 18 '21 at 12:27

I took this from one of a suggestion from one of great Mr Gonzalo Medina (credits to him)

Thank you for the answer. Is it possible to make the such that Fig. 1: is not bold and that there isn't a colon after the figure number? — Carl, Jun 18 '21 at 12:56
