I'd recommend using PostgreSQL and the built in row level security it offers. You can easily make multi-tenant real-time systems using it and https://www.graphile.org/postgraphile/ which gives you an GraphQL api guaranteed to be in sync with your database for free. Also, the transactional support in postgres shines in comparison to mongodb.
