My own use for OneNote was mainly drawing/hand written notes using a drawing tablet. For that use case, I have replaced it with Xournal++
For other notes written with the keyboard, I use simple local markdown files.
All my notes are synced between computers with Syncthing
Even though many phone plans today have unlimited texts, some still don't. A delivery report is basically a second SMS, that you then have to pay for, so I think that is why it is an opt-in feature.
