If I may -
I know Chris, you have done super with your Phals. Personally I think most of the Cattleyas are easier to grow than Phals, provided you keep the bugs out. But, those are best bought from a reputable vendor rather than from the discard table of a Big Box store. Also, in the beginning it is nice to buy in bloom/bud, so you know in what season you might expect blooms. And if you love the bloom, naturally.
Personally, here in NJ, the easiest would be to buy a Fall flowering Cattleya, (C. Chocolate Drop 'Kodama' would be an example). I keep them outside over the Summer, water and fertilize along with everything else and watch the new growth appearing over the Summer. Back inside in the Fall and I will see blooms into October, November.
Some Spring flowering Cattleyas ( as example C. skinneri) might be affected if you keep them under artificial light which doesn't mimic somewhat natural light hours, that is why I recommend as a start a Fall flowering Cattleya.
Then there are some which flower year around, like Potinara Hoku Gem, a mature plant is pretty much always in bloom, mine is.
My two cents....
