Sapote??? But which one.

Hi all. I've moved into a place with large established trees in tropical Australia so think exotics like mango, paw paw, jackfruit coconut, banana etc. these I know, but the sapote's are exotic to me so I need some help that the plant identification app is just not giving me.
I have two trees that are fruiting and the app says Sapote but they are both very different and I would like to know which Sapote I have. One is a little more spread out green fruit, turning maroon. The other is much more straight up and down, green fruit didn't change colour.

First thought was black and white Sapote but then I read the black Sapote (the I've that tastes like chocolate pudding -yes please) isn't an actual Sapote and another app says it's a star Apple. So I have come here to see if you guys can shead a bit more light on it. Photos as follows, first tree overall shape, first tree fruiting, second tree overall shape, second tree fruiting. TIA.
