There are a lot of articles out there on this subject (as this article points out). I think it's increasingly rare to find companies that can't see that value in code reviews. What I'd like to see instead is some surveys of companies doing reviews to find out what's hard. What parts go well, what parts to they struggle with. For example, at my past employer, we tried to pull in a privacy expert on any privacy sensitive changes and a security expert on any security related change. But this was really hard for two reasons. First, it's often not obvious that what you're doing is security/privacy related and probably the worst f-ups will be the one where you didn't mean to do anything security/privacy related. Second, it was hard to scale these "experts" who were domain experts but not an expert in the codebase. I'm sure there are many many other things teams find hard and I think that's really interesting to dig into.
