I've seen minor differences between calculators but all of my builds have been very standard/common configs. Mainly use SpokeCalc or DT Swiss calc.
Like the OP's wheel, most of the builds have been; 3x, 32 or 36H, Shimano standard hubs & 2.0 or 1.8 straight or DB spokes on 26" or 700C rims.
Never ran number of any strange or unusual builds, eg; low spoke count, paired spokes, unusually heavy dish, asymmetric drilling, extreme butted spokes, really deep rims, IGH hub, etc.
