All you need vs Peach is bair. I don't see this whole cornering thing being a problem. You kill her so ridiculously low on YS that it doesn't even matter. FD is fine because I don't feel like explaining it at this hour.
You could still run into trouble on DL with getting "cornered". You have people like Armada who expect you to go on a platform and then they nair you.
