I am new to SU2 and just getting started with running my own simulations. I am wondering if SU2 has built in capabilities for generating .su2 grid files from another file format (STEP file, or any other CAD-like file). If not, what are the best ways to go about creating one's own customized .su2 file from a CAD drawing or other mesh-generating program?

I generally prefer CGNS format for grid input. Most of the grid generation softwares gives output in ".cgns" format. To use ".cgns" files as an input, you have to configure SU2 using this command "./configure --with-CGNS-lib=/usr/local/lib --with-CGNS-include=/usr/local/include --enable-metis" instead of only "./configure". Hope this will help you.

Typically there is another step between generating your analysis model in CAD and running the simulation in SU2. You need to discretize your CAD model with a mesh using a pre-processor such as Gmsh, Pointwise, or other meshing tool. Gmsh and Pointwise are the only tools of which I'm aware with native SU2 mesh file format suppor--meaning either of these tools can export the mesh which you have created directly to SU2's native .su2 file format.

Shainath highlights a good point in that SU2 can be compiled against the CGNS library, and then read in CGNS formatted mesh files--a format that has wider support amongst pre-processing/meshing tools.

GridPro also has SU2 format output mode.
