So how would I spot if a company was selling my email address without my permission?

So if you’ve signed up for a mailing list for a company using a plus addressing email address, mail from that company should be delivered to the appended +folder location. If for any reason you see unsolicited emails to your plus addressing email address, then you know that email has been resold. Adding a +folder appending to your email account allows you to easily spot unsolicited mass email and unsubscribe (or report) those bad actors.
