Some models of Raspberry Pi support emulating a network adapter over one of the USB ports (this might even be the default configuration for some images). This would reduce what you have to bring down to only the USB cable necessary to connect the Pi to your laptop.
You can also get cheap USB Type-C / HDMI monitors which fold flat like a laptop (example). I use one of these while traveling to get a multi-monitor setup for my laptop and are also useful when I need a monitor somewhere I don't have one (like for setting up a Raspberry Pi or when I have my desktop PC in pieces on a worktable).
