Popular operating systems include Microsoft Windows, Apple MacOS, Linux and FreeBSD.

Here we use Linux, specifically the Debian Linux distribution which is a free, open source and community managed Linux distribution with a stable software collection. It has excellent hardware support even for non-free drivers such as the GPU drivers from NVIDIA and network-device firmware from Intel and Broadcom.

Also, the knowledge you gain when using Debian on your workstation will come in handy when when using the SoCs such as the Raspberry Pi as the Raspberry Pi OS is a Debian derivative and when using more open/free SoC-platforms then armbian is another excellent Debian derivative.

On the non-free software side, then .deb and .rpm packages are commonly available. The .deb are as the extension suggest, for Debian and Debian-derived Linux distributions. Thus you will easily get proprietary software such as Spotify, Sublime Text, Discord, Slack, Microsoft Teams and Zoom installed on Debian.

There are also the option of running proprietary applications via overlays such as Flatpak, SnapCraft and AppImage. Or simply using the web-version of those services / applications.
