I've worked with Firebase Hosting for around three years, using Firebase Functions instead of Cloud Run, but in your particular example, you can configure your Firebase Hosting to rewrite requests against your Cloud Run instances as documented in https://firebase.google.com/docs/hosting/full-config#rewrite....

This doesn't require handling an OPTIONS request for every endpoint, which I agree could be fairly simple, but Firebase Hosting configuration could very well be less invasive than this change in the rest of the codebase.

Thanks a lot, I'll have a look into this.
