If you really value a polished web based solution you might consider crypt.ee (It works as a PWA) I've heard ppl say they like it (It's looks like a hybrid cloud storage/document editor), but I don't have personal experience with it. There's a free tier with 100 MB storage, so you can test it if it looks interesting.
