I think most people PC CSP to CFU , i personally don't think CFU is worth a HP on its own. Things may be different now that CSP/CSR sub are once every four as opposed to once every two. If you don't use CFU right now then I would transfer to CF if you can. Also 15000 UR sub for freedom isn't something i would lose sleep over.
IMO if you are going with chase trifecta you should go all in , no cash back cards , you want to accumulate as many UR as you can , you will be missing out on a lot of UR if you are using DC for non category spend.
