So I recognize that having the files securely encrypted is a valuable thing, and that having privacy for sharing is also important. But how do you actually share this without creating a vulnerable point?
Say I wanted to leak some file as a whistleblower, I'd still need to get the link/password/etc shared to whomever I'm leaking to, right? Sorta defeats the purpose when you need some other source of contact, right?
I don't quite understand your question. Yes, to share something with someone else, that someone needs to know what you want to share with them and where to get it from – I'm not sure what you envision the alternative is
I guess it's more asking what the alternatives could be. I don't have the answer, and truthfully don't have much of an idea what is out there to solve that problem.
Is there a system that can get information to someone, maintaining anonymity for the sender the whole way through? Like having an open drop box where you'd be able to put whatever documents you want into it.

Yes many journalistic organizations have secure drop-boxes for this purpose. You have to either trust that their drop-box doesn't record your IP address/other info OR use an anonymity system like Tor or I2P to make sure whatever they record doesn't reveal your identity.
Services like this could be useful if you already have a connection through something encrypted (encrypted mail, matrix, …) but the files are too large for sending without this.
