Inexperience or difference in experiences. I wouldn't necessarily advocate containers as my experience has been mostly "this takes far longer than the gain" (given the OP's scenario).

Meanwhile, my experience is a minimal CICD pipeline takes half an hour once you know manual deployment, and I lose far more having to SSH and run scripts myself than telling a machine to do it for me (not just time but mental satisfaction too).

Though I wouldn't call either fancy in this year. Only past that stage, where the benefits drop sharply for individuals.
