I am the same. Most my projects were infra leaning and I had a very general idea of what I wanted, not clear steps. I learned a ton in the process of cleaning up my home networking, understood network topology and restrictions, how to work around ISP imposed bullshit and setup a home network accessible remotely and securely. I also learned about stacks like Portainer/Adguard etc. Setting up Raspberry pi as a general purpose server including media serving via Jellyfin. Until you do it, even with the LLM doing the heavy lifting, you won't learn how to work around the issues.

I setup exactly one personal finance service/dashboard and one Android app for a specific purpose. Then I stopped because my needs were met. I'm sure I will get into it when I need to again.

You can either use it as a PoC testing enabler in which case it will be bunch of unfinished things. Or you can be deliberate and focused about your goals and the results will match that. Of course being a software developer helps.
