Good plan... I would butt it with a small gap for the caulk/grout. On the stairs, you can use a pneumatic finish nailer to help hold things till the glue dries. Simply nail in the tounge but make sure the pressure is high enough on your compressor to fully set the nail. You’ll pay hell trying to use a nail set to drive the 15 gauge finish nail in if it sits too proud. On the risers, you can simply face nail and use the colored putty that you can get from the floor manufacturer to match the finish. You will need this putty anyway as you get to the last few rows of flooring and cannot get the stapler any closer to the wall. You will have to face nail the last few runs of flooring and the putty will fill the nail holes and you will never see them.
