So, what abilities, knowledge, just stuff would you want a President to have. I’ll start…
Any more?
He should be able to leap tall lobbyists in a single bound and be faster than a speeding powerpoint.
How about if he could tell if your woman has another man?
I guess external genitalia is a given? 
The ability to give free beer to USAF Retirees. I’m really a single-issue voter, just nobody ever picks this issue to run on.
I guess I should have used gender neutral pronouns, huh?
Yeah, and former Coast Guardswomen and men get zoom to the head of the line privileges.
I’m going to wreck the thread by being all honest.
Lacking 6, of course, they would be entirely impotent. But I’d still like them!
They should have substantial inherited wealth
They should have worked near exclusively in public service imbued with civic duty.
The West Wing really screwed you guy’s heads up good, didn’t it?
The more I listen to this fawning for Camelot, the better I understand why the Founding Fathers decided with an elected monarch as head of government when better models were available.
A minimum of 15 years of statewide or national level elected office. I want my president to know something about how government works!
James Tiberius Kirk.
I win. 
He would be the logical choice.
She should read all her briefings, especially security briefings, every day.
She shouldn’t take any more days off than the lowest level government employee (vacation days, not sick days).
She should have foreign policies, but hands-on domestic involvement.
She should have experience in politics. That doesn’t mean she has to be a “Washington insider,” but she had to know how to be a president.
She should have been a good student in college, and have an advanced degree as well as a liberal arts degree. I don’t think it absolutely has to be a law degree.
She has to speak something besides English. Good candidates are Spanish, Russian, Mandarin and Japanese.
She should pick a VP who also speaks another language, and it should be different from her language.
She should understand the importance of evidence-based science and medicine. She does not need to have a degree in a science, but this is why a liberal arts degree is important-- even a degree in pre-law or English literature means the holder has a background in math and basic science. You can’t get a liberal arts degree without knowing how to interpret statistics, add polynomials, or have a very basic understanding of the periodic table of elements.
She should know how to pick advisors, and also how to delegate.
Is he a natural born US citizen?
YES!
Kirk was born in Iowa.
Amanda, Spock’s Human mother, was Seattle born.
Someone good looking! If they are going to speak on tv all the time, give me something to drool over!! 
The President should:
Believe in science and factual information.
Obtain and listen to experts in any relevant field w/o political bias
Believe in and support racial/gender/religious equality
Believe and support complete separation of church and state.
Be honest to the extent possible.
Understand and support environmental concerns.
Support universal health care.
Appreciate the need for good international relations, and honor commitments.
Understand that the office is not for his personal gain and glory.
Be intellectually curious, and able to listen to others.
Be a good leader…choose the right people and and support them.
Have a sense of humor, compassion and humility.
Understand how government works and what the constitution says.
I could go on, but just those would be sufficient.
Ideal president would be some retired general from the Army, someone who’s taken orders and given orders aplenty. Ideally come from a very humble background, grew up in poverty with many siblings in a poor rural region, fought in a couple of deployments abroad, seen the world firsthand, suffered through the hottest heat and coldest cold. Hawkish and a bit neocon, but not as extreme as Bolton. A succinct, common-sense, no-BS, get-it-done guy.
Politically, he would be a split guy - very liberal on practical issues but very conservative on social issues, and he would assemble a Cabinet comprised of half Democrats and half Republicans. I am firmly of the opinion that liberals/Democrats tackle practical issues best, such as taxes, healthcare, UBI, environment, climate change, pandemic prevention, etc. - but that conservatives have it right when it comes to LGBT, abortion, religious freedom, free speech, etc.
This sort of OP has appeared many times in the couple of decades I have been with the SD. What continues to surprise me is the proportion who want a strongman, good at giving orders, uncompromising, military background or inclination, somebody who’d wear the white hat in a Western.
When almost all of your best, (and you have had some right out of the humanity top draw), are nothing like that and almost all your worst are.
YMMV.
