Some linters (eg ESLint) have rules you can enforce for cyclomatic complexity (which is often the problem with long functions, rather than the length itself). In the service I maintain, we enforce a cyclomatic complexity of 5, which is pretty low but it yielded good results

Doesn't a cyclomatic complexity limit of 5 basically rule out the switch statement?

Good question, I suppose it would? On the other hand we do have chunky switch statements (as it allows exhaustive type checking in Typescript), so not so sure now that I think about it, I'd have to check
