Hashicorp tools are quite solid, and give you a lot for free. Ansible can automate host-level changes in places where hashicorp cannot reach. There shouldn't be many such places. Alternatively, if you have the option of choosing the whole stack, Nix/NixOS and their deployment tools. I would recommend staying away from large systems like k8s.
