One of my favorite things about the Prusa 3 series is that you can embed a Raspberry Pi Zero running OctoPrint in it - it fits right inside the power supply enclosure. Bam, you've got a networked Prusa with no external anything.
It is highly discouraged to use a Pi Zero with the current versions of OctoPrint, it just simply doesn't have enough computing power and causes quite a few problems. Prusa really should remove the page in their wiki.
Prusa has a customize build of Octoprint that addresses these problems. As long as you’re not using a webcam with it (and you can’t if it’s embedded anyway), it runs fine, if a bit slow.
