In general, for your major spending, you should use cards that have transferable points (sapphire/reserve, Amex MR,etc) rather than getting pinned down to one loyalty program. You have a tremendous annual spend which could be put to far better use and value of your points.

speaking of Paris, my family of 4 are just finishing our vacation here, purely funded by points through sapphire. 4 one way business class tickets through United (at least 10K$ value) and 2 connecting rooms at park Hyatt for 3 nights (approx 6000$) using a total of 420,000 points. Roughly 4c/point value.
