Are there any immigration programs that one person can apply for and the whole family can go through together?

Canada requires one person to apply and immigrate to the whole family, with one person as the main applicant and the others as secondary applicants; the whole family only includes spouse and children, not parents. Spouses and children can automatically immigrate with the applicant, that is, accompany them. They only need to provide basic information and medical examinations, and no additional mandatory conditions are required. Of course, your spouse and children can also choose not to accompany you and then apply for family reunification immigration.
