We have use debian for years. Our controllers are more equipped than a RPi. We also do our own APT repos in docker, and can create custom APT repos for any client for any project. Our application developers love using APT for development as they can surgically update working images for testing. We have our own mirrors to ensure that things are consistent and rebuildable and use docker for building images from debbootstrap which also have the advantage of making quick test images. The other advantage is that debian is a 'force multiplier', everything we need is there and it allows our devs to go fast. Yocto is fine and is very standard, but we made it work here really well.
