I have the option to build the 3d texture either as int 16, float 16
or float 32 - my preferred format would be float 32. Are you aware of
any major performance hits on using 3d textures in float 32 format?

It will at least eat a *lot* of video memory. A 128x128x128 32 bit float 3D
texture will require 64 megabytes of video memory. There may be more issues
too, or a silent fallback to software rendering.
