I've been doing research to figure out if a druid using wild shape to shapeshift into a beast that is known to be nimble (in the real-world) would be able to prevent or reduce falling damage. For the sake of discussion, I'm talking about reducing damage taken by the current beast form.
I was surprised to read that apparently D&D 5E doesn't even allow using an acrobatics check to halve falling damage (unlike previous editions). I also searched/filtered every single monster in D&D Beyond, and there are exactly zero beasts with acrobatics. Reading the description for cats (as an example), there is nothing in there about benefits when falling, which seems a glaring omission.
So is there any rule that can help a druid prevent or reduce falling damage when using Wild Shape, or do they take the full 1d6 damage and land prone even when falling a mere 10 feet in cat form?

There is no beast feature which reduces falling damage
There are no beast or creature features that reduces fall damage. So, you aren't going to get anything there.
If your Wild Shape form has flight there is an optional rule which can help
In Xanathar's Guide to Everything they give an optional rule for flying creatures and falling part of which says:
Thus, if your DM goes by such a rule, you will have a way to reduce fall damage if you have a fly speed.
But this only works if you are already flying (or at least have a fly speed) when you start falling.
You can't transform into any creature while falling...
Transforming into a Wild Shape takes an action (or a bonus action if you are a Moon Druid), however in 5e falling happens instantly.
Thus, when you start falling there is no time to do anything to reduce your fall damage (unless it is a reaction or readied action which triggers on falling). Once you start falling, you have no chance to use your action or bonus action to transform. So the whole idea of transforming as a way to mitigate fall damage is a nonstarter according to the rules.
...unless you are falling an extreme distance and using an optional rule
The only exception to this would be if you are falling from a height of over 500 feet and your DM uses the optional falling rule from XGE:
