Selfhosted

I have sftp setup on my 2 main PCs and a client on my phone (it's not a server). For the rest of the family who have dual Mint/Windows boots I also have warpinator installed on mine and theirs - it's point to point for the enrolled devices but is currently only setup to work within the LAN.

Primary filesharing is simply the NAS which is visible to all devices on the LAN (can be made available externally but I haven't). This is a recent addition and no one uses warpinator any more.

Edit to clarify I don't have sftp server on phone

My dad found one solution that's specifically for the task (whose name eludes me at the moment), but for me, my nextcloud is a Swiss army knife.

I use KDE Connect. Works well with Tailscale when I'm outside my home network.

I just use SSH+Rsync for everything. I traded two-way sync for minimalism and reliability. I've had nothing but headaches with anything else, especially Syncthing.

My Computer and both Raspberry Pi servers both run Linux and I have Termux installed on my Android phone so OpenSSL and Rsync are easily available.

I made a script that runs Rsync commands from files containing all the information which easily swaps source/target files so I can easily transfer in both directions with a simple command line option. It's reliable and simple and I've had a lot less headaches troubleshooting the rarely occurring issues.

Samba.

Or one time I made my own simple file sharing website

SMB share ( Android <-> Windows/Steam Machine

Samba drive + vpn tunnel. If I'm working on my PC and want to do something with my phone: plainapp

Thumb drive.

I know it's not a dedicated (or that good of a) solution but I just upload stuff to a private room on my Matrix server.

Mostly nextcloud if it's between my own devices.

For getting a file to someone else I had good luck with sharry. https://github.com/eikek/sharry

xmpp and syncthing

Not mentioned but warpinator

All my devices are on the same wirguard network. It allows me to use SFTP to mount the fileservers of the others very easily. Then copying files is as simple as copying from one folder to another.

I use bitwarden send, all my devices already have access to my password database and i can save and download files or text though it. You can also use the URL to let other devices access it if you want.
