For Fujifilm X-Trans files I have found Capture One Pro to work exceptionally well. I use this in place of Lightroom for a large part now, I use this in conjunction with Photoshop CC and Tony Kuypers Luminosity masks panel. Lightroom is a great product that I still use from time to time. For Photoshop and Lightroom I highly recommend subscribing to the Photographer's Suite, which includes Photoshop and Lightroom for $9.99/month, this is a crazy bargain. Yes, you can use them without an internet connection.
