I know a loaded ICE gets more efficient when you look at the specific power output.
But as it is, it's the mpg - the fuel used - that really counts.

Look at the EPA car guide.
Highway mpg are about 50% higher than city mpg (except for hybrids).
So it makes sense not to use a big ICE for the most fuel consuming phase of the ride.

Surely the acceleration phase is also a real drain on a battery in an EV.

Shouldn't those power values be reversed?
Yes, though I doubt Toyota or Honda dared to do that when they launched their hybrids.
Instead they opted for a concept with rather minimal changes to normal car designs.

If they had dared, then essentially they'd have been building an EV with a tiny ICE cruise engine / range extender that never powers the car directly.
Buyers may not have been ready for that.
Probably still aren't.
