what homebrew HF antenna produces the most groundwave?

Vertical antennas make the strongest groundwaves.
Assuming you are confined to a single ground-mounted element of
reasonable height and complexity, Kraus in the 3rd edition of "Antennas"
gives a simple answer in Figure 16-35 on page 569. A 0.64-wavelength
tall vertical radiator produces the greatest field strength at one mile
in the direction of the horizon.
