I dunno, Black Adam treated Captain Marvel pretty dismissively, dominantly and decisively when Billy tried to initially fight him. He only won in the end by tricking Black Adam into defeating himself.
The same Captain Marvel held his own against Superman. So despite everything you're saying being true, it doesn't really bear too much import when discussing how dominant Black Adam was over Captain Marvel. I think you could make the argument that it was as bad, if not worse than First Born's treatment of Wonder Woman and Orion.
Marvel vs. Superman was just writer's establishing the general character. But this is still the guy who has the mentality of a ten year old, who has no idea how to fight, has no idea what powers he has, no idea how to use the powers he knows he has, etc.

And Black Adam effortlessly tooling Captain Marvel wasn't? Again, I'm not disputing any of this. I'm just pointing out that all these facts didn't stop Captain Marvel from giving Superman a fight. He's just that powerful. Had Superman caught Marvel's punch and slapped him around a few times to the point of forcing Billy to flee for his life like Black Adam did, I'd understand your trepidation.
Superman like Black Adam had the upper hand and he even tried to reason with Billy. Shazam isn't yet at his full potential but he will be. As for this fight FB till Black Adam shows more.

That wasn't really holding his own. He punched him and Supes got right back up. Kind of inconclusive, but John's DID hint that Marvel would be fighting everyone, so that will be a better way to judge his power level.
Right. And Captain Marvel got right back up after being sucker-punched by Superman. And they were both fine after they traded two shots each. That's holding your own. And that didn't happen with Black Adam.
^ Taken in isolation, neither do I. But the difference between how Black Adam treated Captain Marvel and how Superman treated Captain Marvel is rather obvious to me.
