Versimilitude for non-magical characters is going to vary based on desired tone and theme and personal taste. Action movie versimilitude is different from gritty realism versimilitude.
In the Avengers movies I was completely onboard with Black Widow and Hawkeye being action movie ultra competent combatants and superspy agents who were non powered humans who could stand alongside Thor and Iron Man doing cool things effectively. In the Black Widow movie when she fell off a roof, fell multiple stories, and hit pavement, went "ow that hurt" and stood up and shook it off that was versimilitude breaking for me even though it is a a context of high action movie competency and in a universe with Doctor Strange and the Hulk. Falling and grappling hook lining to not hit the ground catastrophically was not non-magically action hero versimilitude breaking for me even though it is not realistic.
D&D has varied on what models and tones it goes for with its non-magical characters. In AD&D a high level thief could be modeled on Matthew Broderick in Ladyhawke who never fights and sometimes gets caught but is decent at pickpocketing and sneaking around. A 4e rogue could basically be action movie James Bond their whole career.
