I’m also in the same boat but I find it helps if I have a piece of the white cross on the yellow side because I know I’m flipping that, so if there is an F2L corner next to it I know that is going to be on the bottom, and I can eliminate it as a first pair. Also if the corner is on the bottom I can mentally set that as my first pair and hope the edge piece is visible when the cross is made.
It’s not fool proof but it’s better than not having a plan.
