I've given up on a whole unifying program or application. I've also been burned by either closed source apps or web apps. Very hard to get your data if support stops or you just don't have it. I try to stay as close to plain text as possible these days. Bookmarks - Pinboard with weekly backup to json/text. Notes - A bunch of markdown files in folders (diary,projects,etc). Every day is a new file. I have @tags littered all over my notes for searching. Beauty is that there are many apps that can write markdown and search plain text. Finance - ledger-cli, well, actually my own version with better reporting abilities, in my opinion. Task management - to-do.txt. Again, many apps to choose from to manage the file. Syncthing - Sync all of the above everywhere, plus other stuff. Backup - restic and rclone. Also, everything I've mentioned is cross-platform. Maybe not the application, but the source data is, and has an application that can modify it on almost every platform.
