God damn thank you. This interaction used to be triggered by deep pressing on the keyboard and it drove me insane when they got rid of it, I couldn't find any settings to turn it back on but this works!
My 2017 iPad Pro can do that. I can tap and drag on the cursor to move it. I can also long-tap and drag on the spacebar to move the cursor like a touchpad. I can also drag with 2 fingers anywhere on the keyboard to move the cursor like a touchpad. The first 2 options also work on my iPhone.
