Lifepo4 float setting?
I have not had to deal with a float setting so far with PWM controllers but I have a Victron 75/15 coming tomorrow and reading up on the settings,it is confusing especially the float setting..Some say...

"I'm still confused about float with LFP batteries..Is it better to be in float or bulk the majority of the time?
Off-Grid Garage say's one should set float and bulk the same therefor it is in bulk mode charging when the sun is out vs floating or using battery capacity."
Seems to be mixing two different things. Float voltage setting for the controller vs Float Stage for the battery.
You don't want the controller to be in Float voltage until after the battery is full. Now the battery can go to Float Stage while solar now in Float (after Bulk) can run loads.
Running loads while the controller is in Bulk voltage will reduce the amps going towards charging the battery so best to wait until after the battery is full (except LFP does not have to be full--so running loads might take priority in some scenarios )
Meanwhile if the question is about the LFP Float Stage, you do want that to be at the lower voltage per battery spec.
Also just to confuse things-- your Victron monitor wants the charging parameter voltage used to decide when the battery is full (along with tail current and a time for that) to be related to the battery's Float voltage.
