I've intentionally ignored Kubernetes for a few years. Is it worth looking into K3s instead?

  I've really enjoyed developing on K3s, would recommend.

  It depends what you're looking for. One attraction of k3s is you can get a "real" production-grade K8s running on a single machine, or a small cluster, very quickly and easily. That can be great for learning, development and testing, certainly. K3s is actually targeted at "edge" scenarios where you aren't running in a cloud, and don't have the ability and/or desire to dynamically adjust the cluster size. You can scale a k3s cluster easily enough manually, adding or deleting nodes, but to get cluster autoscaling you'd need to do environment-dependent work to make it automatic. If you do want that, then things will likely be quite a bit easier with a managed cluster like Google's GKE, or even possibly an self-installed cluster using a tool like kops, kubespray etc. (It's a while since I've used any of those, so not sure which is best.) AWS EKS is another choice, although its setup is a bit more complex and I wouldn't really recommend it to someone getting started. And for production scenarios, integration with cloud load balancers, network environment etc. is similarly going to be easier with a provider-managed cluster. It's all possible to do with k3s, but it's more work and a steeper learning curve.
