Php issues - how to remove all old and reinstall new

I’m just getting back to development after a long hiatus when I realized that I needed to upgrade my php from 7.1 in order to work with Laravel. I followed the steps found here : Upgrade to PHP 7.4 with Homebrew on Mac - stitcher.io as it seemed the most popular.

I ended up with my cli being updated to [email protected] but my valet was still running 7.1. After attempting to resolve following these (and other) articles (not necessarily listed in order)

Long story short, I have run into problem after problem all of which involve the cli not matching what’s being served in the browser! Currently, my cli returns PHP 7.3.25 (cli) and phpinfo() returns PHP Version 8.0.0. I’ve been at this for 5 days now and I have a project to deliver soon!

Since I don’t really have any existing projects that require my old set up, I’d like to just reset everything and start from scratch! What I’d like to know is what is the best way to do this?
