That's a good performance benchmark! A list of those by level would be interesting for conceptually placing the power level of warriors. What can a guard, noble, or tribal warrior accomplish, versus a 1st level fighter, 2nd level, etc.
Compare a 5th level Fighter to a Commoner (your average Joe), a Guard (baseline trained professional warriors, including professional bodyguards, soldiers, and members of the city watch) or a Veteran (a professional soldier who has been in the caper a decade or multiple military engagements).
A Commoner has no chance against a Grizzly or Great white shark. It almost certainly kills him in seconds.
Guards can reliably take down multiple Commoners. They have twice the HP (and HD), training in at least shields, light armor and spears, and better ability scores than your average Joe. They're professional soldiers.
A Grizzly bear or Great White shark almost certainly kills one within 2 rounds.
An armed Veteran can take on dozens of Commoners, multiple Guards and a Grizzly or Great White, and likely win. Unarmed and unarmored against the Grizzly or Shark, he dies after around 30 seconds of struggling.
A 5th level Fighter can mow down scores of Commoners and Guards, and should mop up a Veteran, Great White or Grizzly with ease in a few rounds at most;
and he could do it with his bare hands. At this level he is on par with Miyamoto Musashi, Daredevil, the Punisher, or similar low level fictional superheroes and historical legendary warriors.
At level 5 he is literally in T2, and a newly minted 'Hero of the Realm'. He is likely the greatest warrior in his Kingdom, or his name is mentioned among them. In Marvel terms, he may not have Avenger levels of power yet, but he's a candidate for the Defenders.
