G star
I think you made a typo. Our sun is a G type star. K stars, slightly fainter, ~5x more numerous and most importantly stable far longer than epemeral Gs should be better places for 'Earths', assuming the planet's continental drift atmosphere recycler lasts that long.
Big fat Earths with the same density would have higher gravity and some planetoligists claim they would mostly be water worlds with no continents.
