A Greenlee punch would have no trouble with 16 gauge sheet, electrical enclosures seam heavier than that and they cut easily.
Hard to get a smooth cut with a hole saw in thin sheet metal, if you try it take the bit out and use a piece of 1/4 rod, helps some.
2 1/2 might be easier to do with a jig saw.

Free advice is worth exactly what you payed for it.
