As a freelance writer I tailor my proposals by including a representative selection of 3 or more of my previous pieces. Upwork proposals accomodate only one attachment. I imagine the same would hold true for other types of work, as well. How are freelancers getting around this?

Hope this helps.
Not a bad suggestion at all, Stephen.
I'd like to add that if and when I do this personally, I put my my name into the folder name. Such as: PandoraH-Files or somesuch, so the final zip has your 'name on' it. And, when they unzip it, the folder has your name in it's title.
I also add a .txt file into the folder, which is called what-these-files-are.txt. This text file explains what each of the other files are.
I also mention, after my final salutation in the cover letter, then I have added a file attachment.
