Is it possible to do something like
public class PriorityQueue<TValue, TPriority=int> where TPriority : IComparable (note the =int) ?
Before you suggest it, yes, I know I can just add another line:
public class PriorityQueue<TValue> : PriorityQueue<TValue, int> { } But I'm wondering if it's possible to do it as a param.

No. There is no option for default types on generic types in C#.
Definition: “A generic type is a generic class or interface that is parameterized over types.” Essentially, generic types allow you to write a general, generic class (or method) that works with different types, allowing for code re-use.
Use the IsGenericType property to determine whether the type is generic, and use the IsGenericTypeDefinition property to determine whether the type is a generic type definition. Get an array that contains the generic type arguments, using the GetGenericArguments method.
This means that you can put any object in a collection because all classes in the C# programming language extend from the object base class. Also, we cannot simply return null from a generic method like in normal method.

Your second example is often the "best" option available, if you need this behavior.
