Maybe try this? I have great results on the ios keyboard by simply making two changes to the keyboard settings. I turn off auto-correct, and turn off slide to type. I made this transition when they first introduced slide to type, as that setting changes the touch algorithm to prefer where you lift from vs where you tap initially, or at least that’s how it felt. I also have turned off predictive text because I never use it, it’s faster for me to just type out the words than it for me to watch the predictive text.
