Would second all of that re the GRX Di2 shifters. The shape would favour smaller hands.
Concur re the button position, but like you I only use them for my Bolt page changes. Most of the time I just use the buttons on the device.
Having said that, there are occasional duff GRX Di2 shifters - I have just exchanged my nearly new left one under warranty due to a fluid leak. I could never really identify where it was coming from for sure. Rare but a known issue.
