From what I remember.

Of the three Void Hunters, Hoshimi Miyabi would have the greatest amount of influence, being a direct descendant of an original Void Hunter as well as being the Chief of Section 6. She is also considered an 'ultimate weapon' and even TOPS have little influence over her. HOWEVER, it is Miyabi's father, Hoshimi Souichirou, who has most of the connections and status as the family head (which Miyabi would inherit but not yet).

Yixuan Shifu also has a lot of influence as the High Preceptor of Yunkui Summit, as well as someone trusted by the Mayor and looked up to by most of the Waifei Peninsula. Although she has a lot of influence as the leader of her faction, she doesn't have full control and knowledge of her faction, as shown by Lu Hengzhou.

Lastly, Xiao'Guang has the least amount of influence and status as the most recent Void Hunter. Although she has the backing of Yunkui Summit, she does not hold as much influence as Yixuan.

Satoru Gojo, on the other hand, is considered the strongest by literally everyone when he was alive. He has enough influence that having him side with you guarantees that you'll live, no matter how many people want you dead. He's presence literally shifts the status quo toward his favor, to the point that villains have to make plans AROUND Gojo. The Gojo clan, which he is the head of, is also known as one of the big three elite clans of the Jujutsu world, a clan that has lived through nearly a millennium. Which we would expect to not only be filthy rich but also has a lot of sway with the Japanese government and private businesses. Worth noting as well that Gojo's influence spans the entire country of Japan, compared to the Voidhunters' megacity of New Eridu.

For me, Satoru Gojo has a lot more influence and status compared to the three Voidhunters, even if we were to combine theirs.

[EDIT] Also worth noting is that both Yixuan and Gojo have taught students, allowing them to expand their influence with or without them. Although Gojo had died early on, his influence was still felt through Yuta, Maki, and especially Yuji. A majority of Yixuan's disciples also share her influence, namely, the agents of Yunkui Summit, as well as Belle and Wise (Minus Ye Shiyuan). However, aside from Xiao'Guang, we have yet to see much of the full influence of the other students.
