The best answer for Which group does the president most rely upon for day-to-day advice is
The Executive Office of the President
The Executive Office of the President of the United States (EOP) is what we call the various agencies that assist the President in carrying out his role as Chief Executive of the nation. The White House Office (the staff that works at the White House) is part of the Executive Office of the President (EOP), but so also are agencies such as the National Security Council and the Office of Management and Budget. The White House staff and National Security Council are very much people the president will rely on in the day to day operation of presidential business.
