Google Sheets – Can I return a section from an IFS or SWITCH?

I am trying to simplify an if else if else code by replacing it with a single IFS or SWITCH expression. I simplified the whole code to show the problem.

This code works and returns two cell values:

= IF (CELL_REFERENCE = 1)
{
"A"; "B"
},
IF (CELL_REFERENCE = 2,
{
"C"; "D"
},
{
"E"; "F"
}
)
)

This code will not work if only the first value is returned each time:

= IFS (CELL_REFERENCE = 1,
{
"A"; "B"
},
CELL_REFERENCE = 2,
{
"C"; "D"
}
CELL_REFERENCE = 3,
{
"E"; "F"
}
)

The same problems occur when using SWITCH, where only the first value of a range is returned.

Is there a good solution for these cases or just use multiple IF expressions?
