Assuming you don't have another Sapphire product (let us know if you do), I'd recommend the Chase Sapphire Preferred. It has a really NICE SUB right now at 80k points for a $4k/3 month MSR. This special SUB is ending in just a few days, on 6/1. You'll earn Chase UR which are very flexible to transfer to travel partners or you can use them through the Chase Travel portal. It actually earns a decent rate, 3x, on dining, groceries and streaming services if you have spend in that area. There's an annual fee of $95 but that's offset by the benefits and this nice sign up bonus, which is worth at least $1,000.
This sign up is really so good that if you have another member of your family, I'd recommend they also sign up for the card, if your family has enough spend for 2 cards. You sign up first, then create a support link and get an extra 15k UR points if they are approved using your support link. If you want to go this route, I wouldn't dally, given that this offer is ending on 6/1.
