The Young Gamers and Gamblers Education Trust (YGAM) just launched a new online resource - the Parent Hub - that provides parents/caregivers with information and guidance to help support young people to engage with and enjoy the world of video games while being safe online. Although designed for parents/caregivers, this is also a great resource for teachers, youth workers, mental health clinicians, and anyone who works with young people and their families.
(Note: YGAM is a UK-based organization. While some of the info may be jurisdiction-specific, it still offers lots of general information that is useful for families anywhere).
