I suspect this is very subjective. I had a Radio Shack 200-in-1 kit when I was a kid and learned tons from it, working through the book and then designing my own projects. My current project just ties in my doorbell to Home Assistant. I could have built it only using what came with my old Raspberry Pi kit. Once I finish that, I'll be tying in my garage door, another project that uses simple parts. These projects are way simpler than what I do for work (currently writing PLC code for the Navy), but they're still fun.
