First post to get the community going. Here's the list of extensions that I personally use. Most are disabled globally and enabled per project. Feel free to ask questions, give me suggestions, etc.!
Edit: Thanks for the good idea on formatting @NostraDavid. I also converted my list to urls
code --list-extensions | ForEach-Object {" - [$_](https://marketplace.visualstudio.com/items?itemName=%24_)"}
