Synchronizing user (files, configs, etc) between 2 machines - eviltoast

Not a stranger to using linux, but never bothered with keeping things synchronized between devices.

I have a laptop, and a desktop both running Arch (I use Arch BTW) and wanted to investigate the best way to synchronize things from device to device. Just to outline some details, both are running KDE on Wayland, both BTRFS, as well as a number of other similarities such as username.

I want to be able to synchronize certain config files, Documents and Files, and was going to go the Syncthing route.

What are you doing, or what would you recommend to setup in order to have parity between two devices?
