I think it's reasonable to assume a Vulcan woman is 3 times stronger than a human woman. Since in real life on average women typically have 40-50% the upper body strength as a man, you can say on average a Vulcan woman will be somewhere around the strength of an average to above average man. It never was really revealed to my knowledge, but it wouldn't be surprising to me if T'pol had an upper body strength level comparable to Archer. Considering she probably weighs about half as much (I would guess her to be around 110 LBs, Archer probably at least 200 LBs), that isn't bad.
I think T'Pol is weaker than Archer by quite a bit. In Twilight, she was unable to move the debris from her ankle, or even budge it, while Archer got it off her ankle.
Also, it has been demonstrated that female Vulcan's are perhaps less tough and resilient as female humans. In the Maquis two-parter, the female Vulcan gets knocked down a lot.
Like male Vulcans and all Romulans, a female Vulcan is as strong as the writers remember to make them at the time. ENT was terrible for Vulcan superstrength, Archer was always kicking their asses hand-to-hand. Compare with the reboot, where Ayel lifts Kirk by the throat with one hand, Nero makes a giant leap effortlessly, and Spock fights Khan hand to hand.
Well, even Geordi was able to slap around a Romulan in The Next Phase, so inconsistency is certainly a problem. In fact,for a long time on screen, there was never a clear cut example of Romulans having super human strength. A common question that seemed to pop up was "Do Romulans have Vulcan-like strength?" Until Star Trek 2009, that was never really answered!
As for T'pol, I chalk that up to inconsistency, but then again maybe she isn't as strong as Archer. All I was saying is it wouldn't surprise me if T'pol, who is a small person, had the strength of an average to above average man, which would put her around Archer's level.
As for the female Vulcan in Maquis, could be explained by her being weak, even by human standards. I am sure Vulcans, male and female, come in all sorts of strength levels, like humans do, and not every Vulcan is going to have 3 times a human's strength. Take a very weak woman with basically the strength of an adolescent girl who might be able to dead lift 85 lbs, and compare that to Brian Shaw, one of the world's strongest men who can dead lift 985 pounds. That is nearly 12 times her strength. Then you have Becca Swanson, one of the world's strongest women, who can bench press over 500 lbs. How many guys can do that? The most I have ever done in my life was 320lbs, and that was over 10 years ago, when I worked out every day! I would be lucky if I could do 250, now, which I think is about average for a man!
