Perhaps the first changes would be to our dietary track to absorb more energy, so we can change more things!
I always imagined it's a bit like the old Mage vs Warrior vs Ninja (or whatever) selections in fantasy games - you can maximize total area under the curve, or you can specialize in certain areas at the cost of others.
Edit/add - A convergence would also indicate there is global agreement on the "gold standard". Sure, maximizing intellect and longevity/health is easy. But, physical appearance?
Canonically it's Thief/Rogue, analogous to the MMO trinity of "healing, tank, damage" aka "wisdom, strength, agility".
Those can also translate into a holistic way: You gotta have the wisdom to know when to retreat/heal, the strength to endure and the agility to hit/get to where it matters. They don't necessarily exclude each other.
