What is the best way to scatter 20 JSON combinations across database fields?

Question

JSON

I have 20 JSON types. I can determine the type only by the structure of the fields. there is no obvious sign. 10 types coincide in fields by 95%. the remaining 10 have practically no common fields.
Moreover, they differ only in nested fields, i.e. common basis.
{
id: ...
name: ...
objs: {
// this could be the difference between the fields
}
}

I need to put all the data in Postgres. How to be? Create 20 classes? And how then to check which of the JSON maps to which class?

Create a subclass. And inside it, store naked jison, in principle, you only need to search by Id
