One place where I found onboarding effective was one where a target was to have each new hire ship a PR on day 1. This means that all resources are available and working as well as communicating with the team to learn enough about one real problem and solution as well as the entire process loop. Another method I found effective is simply pair programming but seriously for most of the day every day with the same person for a week or two then with someone else. It basically requires pairing to be part of the culture and not only done in specific cases like onboarding to run without being disruptive.
