[MCU] How physically strong is Peter Quill

Quill seems like a regular human at first, nothing special as he goes around fighting aliens, but I've noticed a few things. Peter seems to be on the same level of physical abilities as Gamora, having fought once or twice with no overwhelming advantage on each side. Then I remeber Gamora once picked up a 10 ton ship mounted minigun, and was able to fire it while easily controlling recoil.

Drax is supposed to be much stronger than Gamora, but again they have never showed him being overwhelmingly stronger than Quill.

Quill also manhandled spiderman when they first met, he engaged in hand to hand combat and got Spidey in a headlock with a gun to his head. This is the same spidey who unlocked spidey sense. Spiderman seemed genuinely nervous about the situation.

Then he manages to punch Thanos so hard he shifts his whole body a bit, (Which the hulk could barely do) and snaps Thanos out of a sleep that was caused by a being who could put a celestial too sleep.

Add in the fact the Quill's body is most certainly not regular human, as he can easily survive in the vacuum of space with no protection, just a oxygen supply.

So basically how strong is Quill due to his half celestial genes? Could he beat Captain America in an arm wrestling match? Is he stronger than a normal Asgardian?

I'm curious because the Asguardians movie is coming out, and it will depict an intense rivalry between thor and starlord apparently, which seems odd because of the apparent massive difference of power levels. Or maybe Quill is just super strong and because I've only seen him fight aliens I don't have a good sense of his power?

Seems difficult to really say because baseline humans in the MCU are alot more robust than the real world.  I'd agree that Quill seems a step up from even this tho, especially in his general robustness.
