Bonvoy Credit Card Recommendation

I am a current Titanium elite member and am looking to get a Bonvoy credit card to maximize my points.

Because I already receive the points multiplier from Titanium status, will I only receive an additional 6x points from these cards?

If so, does anyone have a recommendation for which card to choose based on my already achieved Titanium status?

Options: Amex: Brilliant, Bevy Chase: Bold, Boundless
