Personally, I think Zhanshen Square is the best place to shoot the whole picture of the tower. If you want to visit the tower, you can take the subway or bus No. 80 to Zhanshen Square. After taking the picture of the tower during the day, you can consider whether to queue up to seal the top. (Personally, I recommend the Arc de Triomphe, you can see the panorama of the tower and the night view of Champs Elysees.)
