Thank you so much for the PSA. I have been in and out of the keyboard settings screen many times since the update but could not find what was causing the single-tap word selection. Jeeez, talk about an unbelievably annoying feature. Especially bad is how tapping anywhere after the last word in a text area gets interpreted as tapping ON that word, making it impossible to return to the end of an open paragraph with single-tap cursor movement.
