Sorcerer Stat and Proficiences Distribution

I rolled a 96 for my Archer yesterday in a few hours. I just rolled another 96 for my Sorcerer in like 2 minutes and was wondering apart from Strength 18, Dexterity 19, how should I distribute the other stats? I so far have it set to Constitution 14, Intelligence 18, Wisdom 18, Charisma 9.
How would each of those (particularly Wis) affect a Sorcerer?
Also, if you could let me know the best proficiences to select first, that would be amazing!

Thanks in advance.
