If you listen to the explanation Vision gives in Infinity War, the reason Wanda was able to break the Mind Stone was because her powers shared a similar signature to it since she got her powers from the same stone. It's not like she broke it by pure strength alone, nor is there proof that she can break the other infinity stones.As for limitations... We know that she was only powerful enough to contain the bomb in civil war for a few seconds before it became too much for her to handle. We know that her shields weren't powerful enough to protect her completely from the airstrike that Thanos called down. We know that Wanda's strongest TK blasts are not enough to seriously injure beings like Proxima Midnight. We know that Wanda's TK wasn't strong enough to crush Thanos with a single thought and that she needed multiple seconds to slowly crush him. We know that during that time, Thanos was in pain but didn't end up with any serious injury.
It should also be noted that Thanos' strength as he tried to cut Wanda with his sword contributed to Wanda's ability to break the sword. The sword literally started cracking as Thanos pushed down on it, so it wasn't Wanda's strength alone that ruined it.
And yet she did it while also simultaneously resisting Thanos using the Space Stone to help him (which he also uses as a shield against Iron Man at one point). And that, even without said Stone, Thanos could physically overpower 99.9% of the heroes onscreen and pop Vision's forehead open like an egg shell.
Wanda was still a relative noob with the bomb. And that's a low-end relative to catching a collapsing control tower later in that same film (which she only dropped after WM shot her with a sonic cannon from behind), stopping a speeding train in AoU (which she successfully did) or lifting giant alien energy wheels in IW (which she also successfully did). And she had to throw up a shield at the very last moment in Endgame, as she was still gripping Thanos. Wong and the other Earth sorcerers had a moment to fully cast their shield spells (which is clearly shown). In contrast, we see her throwing her arms up pretty much at the last instant. So, unless you genuinely believe that she couldn't do any better whatsoever even if she had a moment to properly prepare herself, that's clearly not a proper representation of her shield strength.
Also, there is no proof that those blasts against Proxima and Corvus were her strongest. The scene makes it clear her priority was getting Vision (and by extension the Mind Stone) away from the battlefield, which is why she repeatedly went for the quick knockdown, grabbed Vision and tried to run.
And yet Thanos knew he was done for to the point where he had his own army decimated just to get free. And considering how consistently durable Thanos is shown to be, especially against energy based attacks, to the point where he tanked point blank blasts from Captain Marvel and has shaken off IW Thor's lightning, that's not a low end for Wanda. Seriously, the scene makes it painfully clear that Thanos was dead meat without assistance. The scene also makes it that clear that Thanos can repeatedly batter things as tough as Vibranium, breaking it in the process, without doing any damage to his sword. So, Wanda breaking a piece off his sword and rendering him nigh-helpless is very much meant to be a showcase of her true power. And Feige doesn't need to reaffirm it in multiple interviews (even though he has) for that to be clear. You don't have to like it, but trying to argue against it at this point is pretty silly IMO.
