I can share files, links and clipboard items between my phone and my computer. Use my phone as remote control while watching stuff. I see phone notifications on my computer and don't miss calls when my phone is in silent mode while I'm at my PC. It has made my life so much smoother.
I'm not sure, because I don't really know, what Find My can do (I think it's an Apple app, right?) What you can do with KDE Connect is make your phone ring to locate it. You can't access the phones location. I hope that was remotely helpful.
Out of curiosity, is this linked to a PC running a Linux distro, or Windows/MacOS?
Edit:
To clarify, I meant this as, "Are you using this with a PC running Linux?" vs. whether it was available across different OSes. Sorry for the confusion, but thanks for the replies that address both interests!
In my case Linux. But as far as I know there is a Windows App as well. Though I can't tell you if it's any good. Maybe there is something for MacOS, too, but I'm not sure.
Thanks! I was asking as I've heard of some jank with the Windows app (which, kind of to be expected given it's having to adjust to a different OS), and I think there is a MacOS version too, but haven't read as much about it & its quality.
