We had a long discussion about this in the past, but it was generally decided that infobox images need to fit these criteria (and I'm excluding the obvious (it has to be a good profile picture)

1) Character has to be alive.

2) Non-Flashback or Flash-Forward (so if a debut is a flashback of them as a child, we would use the picture of them in the series proper)

3) If the above are met, their most recognizable appearance that is associated with their character the closest to their debut. This one is a bit tricky because when you say it out lout, it almost makes no sense (at least to me). But lets look at Sakura. In Part I she began with long hair until she cut it short. Sakura with short hair is her most recognizable appearance in Part I, despite not being her debut appearance.

As such, using each of your examples,

Nagato's image would be the most recognizable image we have of Nagato, none-flashback when he was alive, so emaciated wreck.

Hashirama's most recognizable image, despite being a flashback, is an image of him alive.

Kabuto's Part II debut appearance, is the closest to his Part I debut.

A's more detailed appearance is honestly just a better picture.

Now off the top of my head, there are a few that break this, Pakura for reasons I don't know, has a picture of Impure Reincarnation!Pakura as her image, despite there being a picture of her alive in the article. Madara Uchiha is a more striking, and popular article where we use a flashback image of him alive, but he actually does come back to life in the series proper.
