I have a new advanced men's schola forming and so far it is three equal (baritone) voices. They are doing a fair amount of chant, but as far as polyphonic rep, I'd love to receive some recommendations. A lot of stuff needs tenors...!
It depends on what you mean by "baritone" and whether they're trained. On cpdl, I have a bunch of things by Francesco Feroci, early 18th c. chapel-master in Florence. They're ostensibly TTB a capella, but the tenor parts almost never go beyond e' (sometimes f' but never g') and sometimes not even that high, and the bass bottoms out at G.
Here is my 3-part Gustate et videte arranged for TBB voices (the tenor has one high f), which should be suitable for 3 baritones. There is also an English version "O taste and see" if that is preferred.
And here is my 3-part Psallite Domino arranged for TBB voices (the tenor ascends only to high f), which should also be suitable for 3 baritones. There is also an English version "Sing to the Lord who ascended" if that is preferred.
As per a request, here is 'O taste and see' for TBB. The mode III Anglican chant for the Psalm verses was inspired by the corresponding Gregorian Mode III Psalm tone.
I've also got a bunch of my own 3-part music on cpdl, including a set of the seasonal Marian antiphons. Here's a crappy recording of the Regina coeli, sung by 3 high baritones (me, me, and me). I think it would be fine if you took it down a little.
