For resampling just the surface (just the coordinates, no functional data), the command is -surface-resample. There is also -metric-resample and -label-resample for single-hemisphere format data files (for functional data, myelin maps, etc), which are likely to be more useful for creating a template cifti file.
You can create a template cifti file using -cifti-create-dense-scalar, once you have the medial wall ROIs and volume resolution/structures worked out for your desired cifti space. 4k vertices is already very low, and is missing a lot of cortical detail. If the reason for doing this is a data reduction, you might try using parcellation instead (-cifti-parcellate), where it ideally groups vertices by function (the HCP MMP 1.0 has 180 areas per hemisphere), and doing less mixing of different functions than a simple downsampling.
