I googled it...

https://www.uky.edu/hort/propa...

Everything I read about growing catalpa from seed suggested that it was easy....
but I'd shell the pod... plant seed individually.
It may be difficult to spot the seed... I searched for pics of seed w/o success... but did find this description at Dave's Garden:

It is in the off-season well after summer and fall have passed when chances are high that these seed pods will have viable seeds inside. It seems that the longer the seed pods stay on the tree, the better. A dry seed pod found on the ground or taken from the bare Catalpa at winter's end is the best way to get seeds.

Snug against the inside of the round pod casing were little cloth-like sacks cleverly designed in the same exact color as the inside walls of the seed pod. They had to be coaxed out with my finger. Inside of each beige sack were a few seeds.

Some trees can be difficult... When I got some seed of the honey locust, they didn't come up until I both scarified (cut into seed coat) and soaked in warm water for a week...

When I collected fruit from ginko... I actually did plant the entire fruit...

As far as peach and plum?
I always just planted seed in garden, allowed the winter to break the dormancy... seeds always came up in the spring w/o difficulty.
