What are your biggest spend categories and what's your spend like on those categories? There's more than one Blue and the one best suited to you will depend on spend. It's entirely possible that you should be looking at others cards based on the info you provide.

If cash back is a priority then why the Sapphire? You can certainly do cash back but points are generally worth more if transferred. The CSP is generally better suited to those with relatively high spend. Have you looked at the transfer partners to ensure that you could use the accrued UR points?
