If you are tech-y, Nexcloud with Libreoffice or Only Office or Colabara Office are good options. You can mess around and see what works well for you. I don’t know if this is universal and happens to everyone, but immediately upon finishing my first Nextcloud server, I wiped it and did it all again with my favorite settings/options.

Just be sure to backup to a few different places in case you mess something up. Taking disk snapshots can also help you roll back any screw-ups.
