String height is a highly personal choice. It depends on your skill level, the kind of playing you do, what kind of tone you're looking for, and so on.
Imo, stirrings set up a bit higher provide a superior overall tone. A lower setup may allow one to play faster or easier, in certain situations. But, no matter what choices you make there will be tradeoffs to be aware of.
You can have someone set the action for you, in the beginning. But some adjustments may change through the years as you grow and mature as a musician.
Your choice of strings will also be important to all aspects of your playing. Soft, stretchy strings are easier to "bend" and playing chords can be a lot easier with them. But there are always tradeoffs. Soft, light guage, stretchy strings go "dead" faster, and, imo the have an irritating overall tone.
Heavier gauge strings usually sound way better, overall. Listen to Kenny Burrell, he has a beautiful tone that probably would be impossible to achieve with light gauge strings. Heavier gauge strings also last longer before going dead, and requiring a new set of strings.
It's all extremely personal. There's no need to rush your decisions. Take your time. Experiment with different brands and weights of strings, at various heights.
The very best thing you can do is practice and work your ass off to become the very best player you can be. Develop your overall playing ability, your ear, your musical knowledge. Setup, strings, guitar quality, etc., won't matter if you play like shit.
B.B. King played very light gauge strings. He could probably stretch them all the way around the guitar's neck. While I enjoyed his playing, overall tone was not his high point.
