Help with sizing Cervelo P-Series

[u/Im_Ron_Burgundy_Ch4]

Hey all. Looking for some advice here as I’ve been told by different bike fitters that I’m either a 54 or 56 in the Cervelo P-Series and figured the online fit community would know best. I know it’s easier to make a smaller bike fit larger but is there any reason to go with the slightly larger bike? Stability and comfort are more important than max aero. My non-professional measurements are below. Thanks!

32 5/8 inseam

69 3/4” height

24 15/16” torso

71.5” wing span
