Whilst the jury is still out as to whether there is such a thing as a stupid question, it is true that you are able to make yourself look a little daft by asking something easily found out elsewhere.
Typhoon93,
You could (theoretically) try to modify a modern fighter to take a cat shot and arrested recovery but it would stand you into danger. Best to design it that way from the start.
But in answer to your question Canada, Australia, Italy, Norway, Denmark, The Netherlands and Turkey are A model partner nations. The UK and Italy are B model partner nations. The US services are as you assume. Israel and Japan are Foreign Military Sales customers. Three variants and nine partner nations, so actually less complex than a decent round.
