Magic Wormhole is a popular tool:

https://github.com/magic-wormhole/magic-wormhole
- is that just on linux or also windows, apple, android
  
  Can be installed on Linux, Windows and MacOS. There's an open source client on Android as well. If you don't want the hassle of installation, there's a website: wormhole.app. Claims E2EE and open source algorithm but the client itself is not open source.
  
  The protocol is open, so there are apps that are cross-compatible.
  
  for example
  
  Android: https://play.google.com/store/apps/details?id=com.pavelsof.wormhole
  Windows: https://www.microsoft.com/store/apps/9P564W951H6N
  macOS: https://apps.apple.com/app/riftshare/id1602642908
Syncthings
https://onionshare.org/ perhaps?
Depending on the size signal could work. Syncthing would also do it too for any file size.
- syncthing? like nextcloud right?
  
  https://syncthing.net/
  
  "Syncthing is a continuous file synchronization program. It synchronizes files between two or more computers in real time, safely protected from prying eyes. Your data is your data alone and you deserve to choose where it is stored, whether it is shared with some third party, and how it’s transmitted over the internet."
  
  No, Syncthing isn't a self hosted cloud but a real p2p transfer tool.
  There are discovery servers enabling devices to find each other but files are rarely transferred through them.
  
  Not exactly, nextcloud is more akin to Dropbox where as syncthing just keeps the folders in sync so if you delete or move a file out of the folder the file will be removed on the other machine(s).
  
  But it is peer to peer so you can create a folder, copy your file in and someone else can sync with you using the unique code for your share. The whole thing is encrypted and nobody else can read or intercept the data and it also works great even if you need to interrupt and resume it later . when the transfer has completed if the recipient moves the file it will be deleted from the original folder on your machine. So thats why its best to create a copy to share.
  
  You can do read only shares etc but the official docs go into more detail there
rsync over ssh
OnionShare
Blaze is FOSS and P2P, I haven't tried it but it's worth a mention
- is it encrypted?
  
  I can’t answer that sorry
https://github.com/Forceu/Gokapi

It's along the same lines of Firefox Send and works well. Can be deployed in Docker if you like too.
https://snapcraft.io/wormhole if you’re both using Linux would be a good option potentially.
I use croc or pingvin share
qtox maybe https://qtox.github.io/
if you're sending less private stuff i recommend rakuten funded send anywhere
Resilio Sync is fully cross-platform P2P app for syncing files/folders: https://www.resilio.com/individuals/

I’ve been using it for years and love it.

Edit: Sorry, it’s not FOSS. My bad for not reading the question thoroughly.
- Last i checked it also seems abandoned? The android app hasnt worked right for like 6 years and it never gets updates.
  
  It all still works great for me across all my devices (Linux, Synology NAS, Mac, and iOS) plus it looks like their community forums are still active, and they have packages for Synology DSM 7, which is relatively new. The last iOS app update was 2022, but maybe that’s just a sign that it is stable and doesn’t need frequent updates?
  
  I wonder if you were using their old software called BitTorrent Sync. At some point they did a rebranding, and it could have left you with an abandoned client that stopped working, maybe? ¯_(ツ)_/¯
  
  Bummer that it’s not working for you. It’s definitely one of my favorite apps.
