Your first two pairs are what I'd do in a speedsolve.Haha, thanks! I'm glad if I can be of help, so it's not only me leeching off the infinite wisdom of all the wiser oldies in this thread.I sometimes do M' in the cross, but only if I have 2 opposite white edges opposite to each other and can position them with the M' as first move. I don't think my brain is ready to handle M' moves later in the cross sequence yet.
For the second pair, I found another, possibly even better way while playing around with the cube last week. That would be U F (sexy) F' U R U' R'. Or use sledgehammer for insertion to replace last 4 moves, that might even be more finger trick friendly. It's more moves, but could be faster. I think it's better if the pair already is positioned towards front left, not quite sure if it's worth it with the U move at the start.
The third pair I'd do U2 L U' L' U2 L U' L'.
