Here's exactly what it says on the CIti DoubleCash $150 offer you're talking about:

New Offer: $150 cash back bonus after $500 in purchases within the first 3 months of account opening.1

Cash back bonus is not available if you have had Citi® Double Cash card opened or closed in the past 24 months.

So as long as you wait more than two years after you downgrade to apply for that card again, it doesn't matter that you downgraded at the point, as long as you keep the downgraded card open. (Meaning use it at least once or twice a year, to avoid Cit's notorious cancellations for inactivity!)

OTOH, if you're in the middle of a 24-month wait in that program, downgrading to a card in that program will reset that 24-month clock, which may matter even more.

So unless you were planning to sign up for the Double Cash in the next two years, I'd say put Double Cash on your list.

Meanwhile, I hope you're aware that TYP points expire when you cancel the card you earned them with, even if you hold another TYP card (unlike Chase UR points or Amex MR points), and converting a TYP card out of the TYP program is the same as canceling it from the standpoint of the TYP points you earned with it:

The only way to prevent that is by downgrading to another TYP card, but all other TYP have a signup bonus at least some of the time. But then, since the 24 months is since the last open or close, and if you convert to a non-TYP card you're certainly closing your TYP Prestige, either way you're resetting your 24-month TYP clock, whether you downgrade to another TYP card or downgrade to something else.

So if you have points you want to preserve, perhaps you should downgrade to TYP Preferred?
