I use KDE-Connect. Connects my Linux desktop and any Android or iOS device. It's originally a Linux Application but runs on Windows and MacOS as well. You can send/receive files, photos, clipboard, notifications etc. On Linux I can also use it to control media and use my phone as mouse or keyboard. The pairing is painless via QR-Code. You decide what is shared and what isn't. It works directly over your local network. No cloud servers are involved.
