I do not know if there is something in ardour to do this, but if you
import the final wav file into Audacity, it is very easy. Once you have
imported the track, there is an "Effect" dropdown menu and the first
effect is called amplify. If you select that, the default amplification
will be the amount needed to set the highest peek to 0db.

However, as I (and Ralph) meantioned in passing and Atte went into much
more and better detail. It does depend on the audience. What is
technically best may not be what is best for your application. If what you
are recording will be played along side other people's work, you pretty
much need to follow the same guidlines as they have with reguards to
levels and compression. What sounds best to most people is what they are
used to hearing. So mixdown to -6 peeks or so for your private master to
archive, then tweek it for the finished product to what is commercially
viable in your sittuation. After doing all the tweeks, you find you wish
to change the mix to work with the tweeking :)

This speaking from a strictly Amateur POV. I have a lot to learn about
mixdown and mastering and so in mastering I find the need for remixing to
make my mastering work. Lots to learn.
