There is one benefit using 32bit float.

Usually, VI's output way too hot signals and may be close to clipping 24bit fixed. Doesn't matter whether it's VI or real audio, but if it clips it clips. Now 32bit float is different in one aspect. You can fix that clipping later.

Try this:

#1: open up a session that does not clip. want to be sure? set up a limiter that doesn't allow over -6dBFS out. bounce it out for a test.
#2: create a 32bit float session and import/convert that bounced test file into that session
#3: drive the faders up and/or use whatever plugins you need to get it 100% surely clipping and sounding bad. then bounce it out as 32bit float.
#4: create another 32bit float session and add that clipping bounce into the new test session
#5: use clip gain to bring levels down and prepare to be amazed.
