the easiest for G# is the middle finger down on both hands.
and for A it’s the middle finger and ring finger on left hand, nothing on right hand.
of course you will see the 2nd choices for these but as far as fingering goes these are probably the easiest.
remember to play the previous note long with full control and slide into the next without tonguing, this may enable you to get it easier
of course practice smooth fingering first without blowing at all
