On what surface and what type of 100km?
I would use a very different 23C for a fixed gear crit vs. a fixed gravel ride. Silly example but you get the idea.
If the roads are UK roads and speed isn't an issue I'd run a Durano or maybe a Michy Endurance. If I wanted something a bit quicker I still have 23C Rubinos kicking around, cobbles I'd use Paves, GP4000S are quick.
hippy-
Peak District roads. Not going to be quick.
Are Paves available in 23mm?

This is my point though. If you're not skidding the question may as well be "what tyres should I use to ride 100km?" The answer is dependent on all the standard variances that go into tyre choice and have nothing to do with having a freewheel or not.
Cost, durability, plushness, grip in the wet, fastness, lightness, do i have one in the shedness....etc. It's just a 100km spin around some roads - don't over think it.

Say hypothetically you had to ride 100km on a fixed gear. And said fixed gear was limited to 23c tyres. What tyres would you be looking at?
