What would an earth-like planet with ~2.5 times the radius, ~2.2 g/cm³ density, and 25% oxygen be like?

I wanted an earth-like planet thats larger to fit more continents, but apparentely to have it be larger with gravity remaining the same you'd need it to be less dense.

I also wanted larger creatures to be plausible so I went with 25% (roughly the same as the cretaceous) oxygen.

Im sensing there'd be unforeseen consequences with having a planet like this, so if anyone could point out any that would be super helpful!
