Do you have a domain? If you do, maybe try Nginx Proxy Manager and SFTPGo. I previously used File Browser but the developers made some fairly large breaking changes and I never went back. SFTPGo lets you add accounts easily and I have specific folder setup for sharing with friends. It has a clean interface too. If you don't have a domain, maybe try Tailscale?
