How do you finger Bbmaj7 on piano?
1-2-3-5 with the pinky on the 7th keeps the half-step rub at the top under the strongest reach; the compact lower thirds sit under 1-2-3 with no stretch.
The root is a black key — let the longer fingers (2, 3) own the black notes and keep the thumb toward the white keys where the shape allows.
