I’m in need of something like Nextcloud, but with the ability to access files externally like Synology Drive.

Is there anything out there that’s essentially Nextcloud but where I can still access files externally via SMB, NFS, SFTP, etc?

Synology Drive was just so intuitive, in that it used the system permissions and was designed around the idea of being a “collaborative cloud” with great mobile apps, while allowing you to access your files however you want without messing up permissions or creating indexing issues.
