Well in watching Voyager a half Klingon (B'Elanna) with a meld induced pon farr defeated Vulcan, Vorik.
There we should remember that pon farr made Spock underperform. Not only was he dimwitted, he could be wrestled by Kirk much better than in the utterly uneven fight of "This Side of Paradise".
Would Torres' pon farr infection have made her equally lose ground? Or would the decrease in performance only affect Vorik and others with true Vulcanoid blood in them?
It's a shame Worf never got to have a proper fight with the Romulans he so loathed. In "Redemption II", Sela feels confident a single Romulan guard can handle the captive Worf, and this indeed happens. But when Lursa and B'Etor flee, Worf suddenly evenly grapples with the very same guard, despite just having been tortured three ways from Tuesday. We just don't get to see how that fight would end before Kurn barges in.
Seven a humanised ex/part Borg overpowered Tuvok and in another episode defeated a battle weary Hirogen in the ring. (Yet previously both Seven and Tuvok were strung up and very much overpowered by the very first Hirogen we saw).
I guess we can credit the Borg with things that don't meet the eye, that is, the nanoprobes. But Seven's performance is admittedly uneven. (Perhaps because she's a Borg at heart, and has no objection to losing some first, because triumph is assured in the end?)
Also in Discovery... Burnham, a Klingon raised humanoid faced off with big scary Klingon Kol, much to his detriment.
The point still seemed to be that she was losing, and didn't mind because she had no interest in winning.
It makes rating alien strength confusing.
Also, not all fights count. Wrestling is a good way to judge respective strength. But punching, kicking, the use of knives and the wielding of guns all involve the concept of "threshold strength", the minimum muscular effort needed to deliver the offense, after which all extra force is wasted. And these forces of attack cannot be countered by application of muscular strength, least of all in proportion to the strength of the attack. Say, kicking doesn't take all that much strength, and a burly amazon will die or be permanently paralyzed from a kick in the jaw just as well as a wimpy Records Officer, their muscular strength contributing not an iota to their defenses.
Luckily for us, much of Hollywood fighting necessarily involves wrestling. Especially where it counts, such as Sisko vs. Solok, or Kirk vs. Kruge, or Worf vs. Dax.
