Wrong livelihood for lay person means make sure your job is not those listed above, and don’t break the 5 precepts.
Wrong livelihood for monks is more wide. Since monks cannot accept money, the other stuffs are counted, food, lodgings, medicine, robes etc. Wrong livelihood can mean that some monks use their personal money to buy this kuti, that kuti cannot be stayed by any monk. If the kuti is donated (say a lay person build it and donate it), then it’s allowed to stay. Even if they lay person has wrong livelihood and used their money from that to build the kuti.
For monks, accepting stolen goods, donated by someone is not breaking the vinaya rule of stealing. Depending on what it is, it might be a good idea not to accept it, to avoid the country law persecuting. Eg. if it is just a pirated software (lay person install the software on the monk’s laptop, on their own initiative, as a gift), I don’t think it’s likely to be found out or persecuted. If it is a jet airplane stolen from us military, then of course, don’t accept such things.
Whatever job your family does, you cannot get bad kamma from that. Only if you inherit the family business do you get the kamma from the job.
There’s no issue for monks to receive meals from fishermen. So by that standard, I think there’s no issue for you to live in your family’s home.
