Give the trial a go, you won't regret it.
Runs super light - right off of a USB and in RAM so you don't need to provision an install drive like you would need with TrueNAS. Has all of the support for Dockers, Media server things, VMs, the whole nine yards. Simplicity carries backwards as well - if a drive dies, pull the dead one, add a new one, rebuild, done. It will clear it, stage it, then add it and the volume size will simply expand. Literally plug the drive in, add it to the array and let it do its thing. It has stupidly simple drive management, and takes mixed drives of any size (so long as the parity drive is the largest in the array). I had gone through a couple of other NAS/Server OSs (TrueNAS and OMV) and I really didn't like the layouts of them. So much so that I have purchased 2 instances of it and run it on different servers (I wanted to separate personal/work data from media data.
There is a cost of entry (after a 30 day free trial) but it is worth every single penny. It has been mentioned a couple of times already, but for what you are looking for UnRaid. Outside of large corps that have a ton of red tape, it's very rare to see anyone using Windows for production environments. You could start by deploying minikube to it and deploy your containers on it. Put Ubuntu server on it and start learning. However, I would recommend taking this time to get away from Windows and learn the skills that are required to excel in today's market. It's all too easy with it since it holds your hand through it all. Set up network shares, integrate with many third parties, and so on. You can also deploy docker containers from the UI. Heck, you can even make Windows VMs with video card pass-throughs and so on. With Unraid, you could create multiple server VMs and create a k8s cluster and orchestrate containers with it. Also, knowing your way around a Linux terminal is pretty much required for any development/devops jobs worth their salt.
I have been using it for a few years on a home server and really like it. Maybe Unraid? You can create VMs, Docker containers, etc.
