The highest quality sample rate conversion that everybody wants (TM)
just uses a lot of processing power, so it's best done offline - AKA
converted during import.

Sticking to float is without question the safest way. But if disk
space matters, you know your workflow, requirements and technical
details, you can make an educated decision if you might choose a lower
bit depth - or in the case of the import, Ardour might get a feature to
choose automatically.

It should also be noted that this topic is about the bit depth of the
files that are supposed to be used by Ardour internally only. You
should not normally mess with the files in the interchange directory.
So the compatibility with other DAWs is not of any concern here. There
are various export options (for example Stem Export) for that.
