You can find some good examples in the test files:
https://github.com/microsoft/Power-Fx/blob/main/src/tests/Microsoft.PowerFx.Core.Tests.Shared/ExpressionTestCases/IsType_UO.txt
https://github.com/microsoft/Power-Fx/blob/main/src/tests/Microsoft.PowerFx.Core.Tests.Shared/ExpressionTestCases/AsType_UO.txt

Some of the test cases:
AsType(ParseJSON("{""foo"": true, ""bar"": 1.1}"), Type({foo: Boolean, bar: Number}))
AsType(ParseJSON("{""Name"": ""SpongeBob"", ""Age"": 1}"), Type({Name: Text, Age: Number, Aquatic: Boolean})).Name
IsType(ParseJSON("{""foo"": true, ""bar"": 1.1}"), Type({foo: Boolean, bar: Number}))
AsType(ParseJSON("[{""a"": ""Hello"", ""b"": ""2012-01-02""}, {""a"": ""Hi"", ""b"": ""2012-01-03""}]"), Type([{a: Text, b: Date}]))

So, when using these with user-defined functions, do we pick, "UntypedObject"?

A working example of a user-defined function using a user-defined type in App.Formulas would be very helpful! 😀

...thank you!

These are the types we get in Power Apps studio right now:

Here we go. This works great:

fxMyPerson := Type({FirstName: Text, LastName: Text});

fxPeople := Type([fxMyPerson]);
