Well, powerful shinobi are exceptionally versatile in combat. That does not mean they have to know many techniques, a select few would do, but it does depend on the innate potential of the said shinobi. So to cover the basics:

1) Nature Release 1:

Affinity for a specific element used for powerful offensive purposes( Fire Release: Fire Dragon Flame Bullet, Water Release: Water Dragon Bullet Technique, Lightning Release: False Darkness etc).

2) Nature Release 2:

Second affinity for a specific element used for enhanced defensive purposes( Water Release: Water Formation Pillar, Earth Release: Golem Technique, Swift Wind Wall etc)

3) Taijutsu

Something akin to Bee's Disturbance taijutsu would be invaluable. As close-combat is almost guaranteed to occur. Also, focusing in taijutsu would build up stamina, durability, reflexes and reaction speed.

4) Genjutsu

Genjutsu is rarely used in the series, as most characters seem to only rely on ninjutsu for combat. A powerful genjutsu would be quite useful against stronger foes. Something akin to Bringer of Darkness or Ephemeral being effective in combat would be dangerous. Would also aid in knowledge of genjutsu resistance.

5) Summoning technique

Particularly overlooked imo, summoning creatures, reverse summoning, collaborative jutsu, makes this jutsu a tactical advantage in any situation.

Of course this is just my opinion on the matter, and most strong characters in Naruto are specialized in a particular field, while having additional jutsu if need be. While others are simply prodigies that excel at everything.
