I really love the Switch Axe because it's very versatile. It has enough range to hit really tall monsters / chop at tails, etc. And it also is a very quick weapon that can deal a ton of damage quickly. Axe mode has more reach and good power. Sword mode is a fast / weaker version of the Great Sword (sort of), but each Switch Axe has access to its phial ability in Sword Mode (paralysis, elemental damage, etc, depending on the weapon). It's a cool weapon, but it takes a while to learn all the in and outs, since you're sort of playing with two weapons in one. I think you could pick it up as a new player and be okay with it, but you'll really have to invest some time to learn it to unlock its true power.
And yeah, ranged weapons can be very tough for new players to grasp. I really recommend getting to know the game a bit more before diving into those.
