Welcome to the 3D printer club Mark, hope you'll have lots of fun and creative stuff you can make .yes they are easy these days just find a file and either Wi-Fi or SD card it to the printer and let it do it's thing . Mine can do both but prefer SD card.
My printer exploded yesterday, accidently poked a screwdriver into the hot end fan and sheared off 3 blades which unbalanced it and ruined what I was printing. So have got 4x on order from Ali at the same price as 1 on eBay and postage time.
I sent deano a file the other day of a pinto intake manifold which we've both been working on, I finally cracked it and it's nearly set for printing after a bit of tidying up , all done on the tinkercad site. Fusion 360 is still a bit to absorb for me, blender is ok, gimp is another, there's so many to use these days, it's what your needs and complexity your wanting.
Funny thing, I've never done a benchy, it's usually the first thing everyone prints .
