Since our board is good and can improve, I'd play 24/19, preferring to hit rather than be hit with 18/13. Then the one. That's tough. If we split the 18 point and get hit on 17, we're left with only a few indirect shots. Preserving the 18 would block 8s and 44. I'd play 6/5.
24/19 6/5

This is a somewhat unusual position where the irrelevance of
backgammons makes a significant difference, even though it might
seem that the backgammon is a long way off.
