Returning null: Everything is fine, but the stuff you asked for does not exists which is expected to happen.
Throwing an exception: There is a problem - it is stopping me from getting the stuff you asked for, or it is really freaking weird it is missing - your data model probably exploded.

Two VERY different situations and if you handle them both the same - ehh... well.. ehhh... yikes.

Unfortunately it is not always clear-cut which is best, so you often end up wishing the API you use does "the opposite" (Queue.Dequeue, I am looking at you, it's not a freaking problem a queue is empty - it is vary often the desirable state). Some API's have both (TryDequeue would be nice).

But at least now I can look at the return type and know right away if whatever I call can return null or not.

Don't follow your comment on Linq. I think you have a misunderstanding of the nullable type system. All that will change is the return type of FirstOrNull will be of the nullable type - so if it is strings, FirstOrNull return type will be string? instead of just string.

Normally the compiler is on top of it, and will not bother you at all if you check for null before assigning it to a non-nullable string. If the compiler bothers you, maybe ask yourself if you really want to proceed with some code the compilers type system can't understand. If you do, simply override the null check with a !
