I like LocalSend, much easier than KDEConnect, and also on F-Droid. But I have to confess that I usually send photos via Signal on mobile to myself and then open Signal app on the desktop to download it.
I have been using it for the last ~6 months and found it to be very useful and easy to use. Transferring stuff between Android phones, Windows 10 & 11 PCs and a Steam Deck (i.e. Linux PC) has been a breeze.
I have not used Landrop but looking at it from the outside, Landrop is version 0.4 and has received no development for 3 years now. LocalSend is past 1.0 and still in active development. I'd rather use LocalSend then instead of something abandoned before it was deemed complete.
Thanks, this tends to be functionality I dont need that often but when I do it's frustratingly difficult finding something that doesnt feel like it's going to need me to sign over my soul so it's good to know about other open source solutions.
