One feature of Dropbox I take shameless advantage of is sharing files (not pirated material, FWIW) via a link. Suggestions on a replacement for that, since Syncthing can't do that?

This.

I found old save games still shared via Dropbox or Google docs that work 7-8 years later.

The combinations I see in other comments are not going to survive that long.

ipfs + the cloudflare gateway is great for that, I use it for sharing files here. You don't even have to install anything and can use EG: https://anarkrypto.github.io/upload-files-to-ipfs-from-brows...
