Coordination chemistry simulations
Have you tried using GFN2-xTB (https://github.com/grimme-lab/xtb)? It is essentially the fastest method you could use, after forcefields, but is designed as general-purpose tool. I haven't tested it with Zn, but it's worth a try.

CompChem Project Ideas for an Undergrad?
I would recommend getting xtb (https://github.com/grimme-lab/xtb) and exploring some possibilities. The calculations are lightning-fast, so you have a quick feedback loop and you can quickly test different ideas. You can look at recent publications to get an idea of what people are doing.

Considering Julia versus Fortran for a project
the xtb and dftb programs are actually excellent example of well-written, clear, modern fortran codes. I've learned more from reading these codes than from any other resources.
