My understanding is that my physicsl cards will be disabled

The Travel membership contains one (1) Travel Card. You will be able to continue using this card both physically, in Apple Pay / Google Pay (if available in your country) and of course online.

However will I still be able to use my virtual (cloud) credit card

Online cards are not included with the Travel membership.

and make iDeal payments

Other payment methods are not included with the Travel membership. You won't be able to use bank transfers, direct debits, iDEAL and Sofort. You can only make payments with the Travel Card as a Travel member.

Also what happens to the annual payments that are running still.

What kind of annual payments? As bank transfers and direct debits are not possible with the Travel plan, you won't be able to set up or use standing orders, either.

Also will I be able to select the account that I want to keep?

You won't have a real bank account anymore, only the "balance" on your Travel Card.
