there is enough good software out there. If it's only file sharing, then I'd prefer 'LocalSend' . For anything more complex, like send clipboard, push notifications or remote control is 'KDE Connect' my first option, since it's also available for almost any platform.

I've personally had great success with KDE Connect on the LAN for all that (and also as a handy touchpad / keyboard input device for PC). It's one of those "Just Works" tools I always reach for. Also have found SyncThing to be really excellent for keeping folders auto-sync'd between devices. (One personal use-case example for that is keeping my "Pictures" folder in sync between my phone camera and a local folder on one or more of my PCs.)
