There are already arduino-based products that are suitable, but as stated before, a large part of the problem is getting past the "maker" association. If you look at Industruino, Controllino, Ruggeduino products, and then the domain-specific arduino variants such as those for home automation, automotive hobbyist, lighting control, you'll probably find a lot of already OSH/OSS arduino-based hardware on the market. And on the development side, ditch the (beginner-friendly?) Arduino IDE for VS Code and the PlatformIO plugin and you're all set.
