Synching is for syncing your files across several devices of yours. CryptPad is for working with other people, possibly at the same time on the same document.
The tools donc comapte, the needs are very different, and you might find them both useful in different situations.
It seems to me syncthing simply doesn't need anything more, you just use the desktop application of your choice for editing your documents.
And yes, you are kinda locked into CryptPad if you don't export your documents as you go. The server not having your documents at a central place and all the documents having different decryption keys means it's hard to provide a simple "take out" zip export. I guess some automation tool accessing your browser profile could be built to help with this.
