I've never seen a comprehensive list of apps and manufacturer-installed bloatware. The problem is that even if there were a generally agreed list of what actually is "bloatware" it would be hell to maintain the list: every manufacturer adds their own set of apps to a phone, this will change with major updates, may change with minor updates, and in addition carriers add their own crap. It isn't even necessarily the same for phones from the same manufacturer running the same version of Android. So keeping track of it and maintaining a list would be a major job.
But there's an important thing to know: not all system apps can even be disabled. The idea is that they are supposed to stop you disabling things that would have really serious consequences (e.g. crash the phone and leave you unable to log back in), though many manufacturers abuse this to stop you disabling their apps or even bloatware they've been paid to install (as Samsung did with some ordinary commercial third-party apps, in no way essential to Android, that they installed on my old tablet). But the point is not that manufacturers abuse this protection, but that it should not let you disable anything that would really break the system, which means that if you can disable it then it won't cause any permanent harm. Of course you may lose some functionality, but if you don't use that then it doesn't matter, and if you do you can re-enable it.
So basically, once you know what something does, and know it's not something you care about, then feel free to disable it. One caveat though: don't disable Google Play Services unless you are really sure, because there are a surprising number of things that depend on that and it's not just going to break Google apps but also a number of third party apps that use things it provides.
