USBs aren’t convenient enough. I’ve done wifi sharing via FTP, which didnt require WAN. Ftp was slow to set up. My bluetooth’s bandwidth seems very small?
A 1 click to install app across multiple devices, that only uses LAN, would be ideal. Right now, I just transfer files with element
Syncthing
As someone else said, Syncthing. It’s pretty much exactly what you’re looking for. We use it internally at my company where we use all major OSes and devices.
What devices are we talking about? For phone to PC is use KDE Connect. It’s reasonably fast 🤔
Yeah this is what I use, however it’s not just for phone to PC, you can use it between any devices (although I couldn’t get it working on a TV running android).
Trebleshot between phones and phones <-> PCs.
It is on F-Droid.
Between PCs in a same network, uses Samba (some DEs allow to share folder in folder properties) or if you are in a dynamic environment (school) try KouChat which allow sharing files and not only LAN chat.
What devices are you using?
Phone to PC
You could send files in your LAN via WebRTC
web rtc is awesome
I think https://snapdrop.net/ might work for that?

I use KDE Connect and Dragit.
Bluetooth does have very small bandwidth.
This version of the Bluetooth Core Specification was released before 2005. The main difference is the introduction of an Enhanced Data Rate (EDR) for faster data transfer. The bit rate of EDR is 3 Mbit/s, although the maximum data transfer rate (allowing for inter-packet time and acknowledgements) is 2.1 Mbit/s.

Also newer bluetooth is faster, but sends the data via wlan
Version 3.0 + HS of the Bluetooth Core Specification[75] was adopted by the Bluetooth SIG on 21 April 2009. Bluetooth v3.0 + HS provides theoretical data transfer speeds of up to 24 Mbit/s, though not over the Bluetooth link itself. Instead, the Bluetooth link is used for negotiation and establishment, and the high data rate traffic is carried over a colocated 802.11 link.

I use croc
I use Warpinator for that
The simplest to use is O&O File Direct, it very easy to use and encrypted end2end. But the problem is, it is not FOSS (Freeware) and only for Windows. Sad. I have put it just in case it is useful to someone despite this, because it is really good and safe.
