What can fluorine explode with?

Seriously?
Fluorine is reactive with many substances. Which would prevent explosion - the reagents would ignite on contact and therefore be unable to mix and accumulate for later explosion.

Which substances have such moderate reactivity with elementary fluorine that initial mixing without immediate ignition and explosion sometime later is a hazard?

It appears carbon monoxide and fluorine are not quite hypergolic:

Fluorine most electronegative element with Cesium metallic ,less electronegative element ( no radiactive) should be a explosive reaction.

In small amounts and carefully controlled conditions, it's surprisingly tame, but very cool to see:

Caesium should not be easy to explode for the same reason as fluorine - reactive. Soft and low melting metal, hard to grind to powder because plastic rather than brittle. And would ignite straight away, rather than mix and only then explode.

That was a pretty light on the little video clip that (name invisible) has offered for us to see if so chosen. I expected far for reactivity but still I liked the light

And have similar liquid ranges. Fluorine -188 to -220 degrees, carbon monoxide -191 to -205 degrees. Considering both are low polarity, I should expect them to be miscible.

Are mixtures of liquid carbon monoxide with fluorine (and oxygen) sensitive to impact?

Seen a video once of flourine gas being sprayed over a raw chicken and bursting into flames on contact.

Which is what does not explode. Ignition on contact prevents the reagents from mixing and then exploding later.
Raw chicken is not very porous either.

Liquid oxygen does not immediately react with many flammable substances (even gaseous oxygen does not) and oxyliquits are popular explosives. So which substances are suitably (or rather, dangerously) sluggish so as to mix with fluorine and explode later?

I thought they chlorinated chickens...

No u flourinate a chicken.

Understood the joke two days ago.
Only thought it was a a spelling mistake for 2 seconds.

Good one :D
