flac cannot handle 32 bit *floating point*. the link you provided reads:

"FLAC supports linear PCM samples with a resolution between 4 and 32
bits per sample. FLAC does not support floating point samples"

That said, Audacity only has FLAC export options of 16 & 24 bit depths.

Ardour supports 32 bit float export to file formats that allow it. FLAC
does not.

Note that technically WAV does not allow 32 bit float. You really need
"WAVEX" for that. Sensible audio file I/O libraries can handle it, however,
even though technically it violates the WAV specification.
