The answer depends on what you want to achieve. If you want to learn to play guitar the way most folks play the guitar, standard EADGBE tuning is your best starting point. Almost all YouTube tutorials, method books, and other means of self learning will be using standard tuning. So any other tuning would prevent you from benefitting from any type of learning resources geared towards beginning guitarist.
If on the other hand, you simply want to get to a point where you can actually play something that sounds like music as quickly as possible, some of the open tunings may get you to that point faster. Many open tunings (Open E, Open G, etc.) will allow you to play a chord by simply strumming all 6 open strings (can't get any easier than that)! You can add more cords by using your index or middle finger (or both) to hold down all six strings on one fret. Then by strumming all six strings while barring all six on a certain fret, you will be playing different chords depending on which fret you are pressing the strings down on. With an electric guitar and super light strings, you should have no trouble holding the strings down on one fret with one finger or perhaps using the other finger on top of the one for extra leverage.
It should be noted that the one finger barre chord in open tuning will only allow you to play the basic major chords - but there are thousands of songs that only use 3 chords (the I, IV and V).
If you start with an open tuning and learn to play a few songs that way, at least you will be deriving some instant gratification that might inspire you to continue to improve your skills. You will also be building some finger strength, practicing strumming patterns, and learning to keep a steady rhythm. All of these skills will benefit you later when you become more interested in challenging yourself to learn to play in standard tuning.
If you want to try open G - tune your guitar like this - DGDGBD. Note that with standard tuning, if you play the 2nd, third and fourth strings, you are playing a G chord. But it's hard to miss the other strings. So if you just change the tuning of the other three strings so that they all play one of the three notes in a G major triad, then you can't miss.
For other alternate tunings, you can search on line for how to tune them.
Good luck with learning the guitar. It's difficult in the beginning, but once you start getting the hang of it, playing guitar is very rewarding and can provide a lifetime of personal enjoyment and relaxation.
