There's a difference between professional warmth and "we're a family". The latter usually comes top-down, from management and is fundamentally disingenuous. It's often a self-serving way of trying to get you to treat the company as your family, while company leadership still won't hesitate to lay you off in a mass zoom meeting. It's fine to be friends with co-workers or managers, but don't let companies obscure the fundamental nature of the relationship.
