Shadow Clones, FTG, and (Sasuke's) EMS are probably my top picks. With shadow clones and FTG I can basically be super productive etc and with FTG alone time is cut down from everything - imagine having a marking at home and at work, which would totally eliminate travel time. The EMS is more for the (perfect) susaoo than anything else, due to it being such a good form of defense. Some other things that I'd quite like to have are sage mode (heightened sensory ability would be super cool) and Amenotejikara, to allow for close-range teleportation to places where I might not necessarily have a FTG marking already.

the clone always does what the caster wants. so if the caster creates a clone and says read this book on astrophysics the clone will do exactly that

Surprised nobody said this yet: Give me Hagoromo's Chakra transfer ability and I'd go around turning as many people as I could into Chakra users, under the condition that they will go on to do the same. Then wait and let (un)natural selection do its part

ummmmmmmmmmm Ever heard the quote "if everybody's special, then no-one is"

Nah fuck that if I'm walkin on water my peoples is walkin on water wit me

LET'S GET THIS NINSHU

If I had to chose any of the powers, abilities, skills, or jutsu from the Naruto series (manga and anime) I would either chose obito uchihas mangekyo ability (Kamui) or naruto's signature shadow clone jutsu. in the former case it would save a tremendous amount of time traveling between locations (although it is never made entirely clear whether obito has to have visited a given location to teleport himself there via his timespace). In the latter it would save one from needing to ask for assistance in stuff because one could just call up the requisite number of clones (assuming ones chakra and life-force are strong enough to divide accordingly) plus one could make a more defined difference in the world by way of ones clones. for example the original and two other clones would stay in ones immediate locale and preform the duties expected of oneself. other clones could be sent to Indonesia to help with the recovery effort. Plus as Kakashi illustrated during Narutos change in chakra nature training when a given number of clones disappear the original gains all their knowledge and experience. the only real downside (also well illustrated during that same training) is that depending on the number of clones all that cumulative experience comes at the cost of cumulative fatigue as well.

Absolutely right. No one will be "special" because of it, but "everyone will be better"

No doubt that was Master Hagoromos hope and intention as well but as history (regardless of much black Zetsu twisted it) shows a great good only remains so for a short period of time (and sometimes even within the lifetime of the instigator of the great change it begins to be perverted and corrupted). Besides which no matter how intention one might have in mind for giving others power they would otherwise both lack and be ignorant of it is ultimately up to the person given such power what they will do with it.

Da powa 2 becum an ADMAHNIZSTRAGHTOHR, having the Byakugan couldn't hurt either, for reasons you don't need to know :)
