Some changes I would make:

1. Always use `git switch` instead of `git checkout`

2. Avoid `reset --hard` at all costs. So for the "accidentally committed something to master that should have been on a brand new branch" issue, I would do this instead:

    # create a new branch from the current state of master
    git branch some-new-branch-name
    # switch to the previous commit
    git switch -d HEAD~
    # overwrite master branch to that commit instead
    git switch -C master
    # switch to the work branch you created
    git switch some-new-branch-name
    # your commit lives in this branch now :)

3. I'd apply the same to the `cherry-pick` version of "accidentally committed to the wrong branch":

    git switch name-of-the-correct-branch
    # grab the last commit to master
    git cherry-pick master
    # delete it from master
    git switch -d master~
    git switch -C master

4. And also to the "git-approved" way for "Fuck this noise, I give up.":

    # get the lastest state of origin
    git fetch origin
    # reset tracked files
    git restore -WS .
    # delete untracked files and directories
    git clean -d --force
    # reset master to remote version
    git switch -d origin/master
    git switch -C master
    # repeat for each borked branch
