re: Due to the lack of continental plates and tectonics
Actually, the theory of a global resurfacing event on Venus comes from crater counting. The entire surface of Venus (except for local lava flows) has essentially the same statistical crater density, saying that it is all the same age. Comparisons to the Moon suggest that that age is ~750 ma.
There are other ways to cut the cake - you might just be able to combine a cessation of plate tectonics worldwide with loss of water and the end of significant surface erosion, to give a similar result, but it requires leaning on the scales a bit...
