Budler gives great advice. You could start a little smaller for your first grow. I think either CMH or LED are great for new growers. I myself had an excellent first grow with a MarsHydro "300" watt LED, which goes for less than $80 on Amazon. I soon got a second one of those, and then a Roleadro "400" watt COB LED, which makes a nice, bright, white (not blurple) light, which is awesome for small-medium plant veg. I use that in my 2nd stage veg for when my plants are about the size of my hand until they are big enough to go into the flower tent.
Those MarsHydros grew me some really nice, sticky, STINKY buds on about a 3 ounce plant, perfect for a first timer.
