Do they need to be able to fight across the entire Pacific? Their most likely adversaries are right next door and their most likely ally is the dominant naval power already.
I any money spent on a large carrier would probably be better spent on other things. You can spend 10 billion on a single carrier or get a fleet of ~100 F-35s. I would guess mid-air refueling and more planes will get more sorties over likely targets in a conflict than a carrier would.
I also don’t think carriers are going to be the dominant sea power force in a future peer conflict. I think the submarine will dominate the next war. The carrier will be regulated to power projection after the sea is won and made safe to operate in.
Surveillance, recon and range of weapons has drastically changed. Satellites have the capability to identify a surface fleet and long range weapons are now able to be fired from long distances, find and hit their targets.
I think a couple submarines can effectively negate a carrier task force by just forcing the task force to keep their distance by the threat of a missile launch coming from a patch of seemingly empty see. Any surface ship hunting them is at risk of suddenly becoming the hunted themselves by the submarine or by any land based defense system that are in range.
