I am wondering how I express my feelings about an action that has already occurred/been performed.

For example, how would I state the following:

• I am happy to have returned home.
• I am sad that I missed the train.
• I am upset that I finished the apples.

My best guess for the first example is the following:
帰ったことが嬉しい。

However, I am unsure about my usage of こと. If it is correct are there other ways of writing this kind of sentence that I should be aware of?

I know that の is also used for verb nominalisation but as far as I could find online that would be wrong since the two actions are being performed at different points in time, right?

帰った【かえった】ことが嬉しい【うれしい】。
