The former approach is more like the Unix way: each tool does one thing and does it well. I prefer that because I can then assemble a workflow that works for me. It's easier to build pipelines when you can drop in each piece one by one.

All-in-one tools almost never do things exactly the way you want. They have a higher barrier to entry as well as a stronger lock in effect than smaller tools. If I fall out of love with venv, I can replace it with Docker. I can't just do that with an all-in-one tool.

Having said that, poetry is quite well designed and I do encourage junior developers to explore it for themselves instead of just doing what I do. If I was a junior developer today I might be quite glad for a single all-in-one tool that gets me on my feet with good practices from day one.
