Certainly in the UK (GDPR is unaffected by Brexit) andprobably in other European countries too there is already reliable *free* online advice for voluntary groups about GDPR compliance.
I'm not an expert on this but have to deal with it for work, for Mastodon I think the new functionality to download your data is a *big* step towards compliance (and won't go unnoticed by regulators, especially with FR govt having involvement with at least one instance)
