You should learn basics of Vim just for quickly editing config files on servers.

For programming I don’t think the speed gains are worth it. It would take more time to learn it than I would shave while using it.

I use the VS Code built-in git support for making commits, and fall back to the CLI for anything else.

You won’t have trouble remembering commands once you use them often enough. And you don’t need to know all of them, just the ones your workflow uses. My toolbox is commit, checkout, status, reset, rebase -i, merge, bisect. That’s all I need day-to-day.
