Capture One has one of the best X-Trans demosaicing engines around and it has very good color reproduction. If you want to give it a try there has never been a better time since the Full version and Fujifilm version are on sale. The Full version will let you use any camera with Capture One, but they also sell a version that just supports Fujifilm cameras, which can save you some money. As a bonus, you will also get a free upgrade to Capture One 21 when it ships.
