ST's website does not use the term M4F. Also there is no filter for Hardware Floating Point Unit in parametric search so I guess ST includes floating point unit in all M4 parts.

Yes all Cortex M4 from ST include a floating point unit and are thus essentially Cortex M4F.

Other manufacturers do this differently. Like pointed out in the comments there is Microchip with the SAM4C has a dual core implementation where one has a FPU and one has not.

So keep looking when you change to a different manufacturer.
