What is the duty of one whom Allah Almighty has favored with specific blessings towards themselves and towards others, and what responsibilities arise from this favor, such as inviting those whom Allah has guided, spending for those who possess wealth, and helping others for those whom Allah has granted knowledge or intellect?

The Prophet, peace and blessings be upon him, encouraged charity, generosity, solidarity, and benevolence. He taught that whoever possesses surplus wealth or knowledge should share it with those who lack wealth or knowledge. The zakat of knowledge is fulfilled by disseminating it, acting upon it, speaking the truth, enjoining good, and forbidding evil. Every person of virtue should assist others, and this is a recommended act unless it becomes obligatory to ward off harm from the less fortunate. As for calling to Allah, it is a communal obligation (fard kifaya), and it may become an individual obligation (fard ayn) depending on one's capacity and knowledge.
