I just checked and I was wrong above. The wrenches needed are 15mm and 16mm.

I know I did a bike very recently with a 15/17 combo though because I remember being surprised about it because 17mm isn't that common. Perhaps it was the Shimano 3S I did the other week. I must have gotten the two mixed up.

The Park cone wrenches come 13-14 and 15-16 which is an issue unless you also have the 15-16 combination as you can't use both sides of the wrench at both times. It is nice that they have this selection so you don't have to buy a whole second set of the Park 13-14 & 15-16 wrenches

You really do not need the 17-18mm wrench as those are pretty darn rare in my experience. When you do run into the rare 17mm it is usually on the outside anyhow and you can mostly get away with using a regular wrench on the outside unless you are must adjust the cone while on the bike. Even so, you can buy all four of the wrenches on Amazon for under $30 shipped via that link I gave above.

if you buy cone wrenches stay away from the Avenir set. They seem like a great deal for 2 matching multi-wrenches but I've got a set of those and they are almost totally worthless. If a cone is even remotely tight the wrenches will strip getting it loose. I never over-tighten them when assembling so they are fine for that IMHO but you can't use them to take off old cones that have been on a long time or have been over-tightened from the factory. That afore-mentioned Shimano 3S was so tight that I almost killed my 15mm and was using a standard 17mm on the outside. That Avenir combo cone system wouldn't have lasted a second.
