First credit card

Hi everyone, I’m 19 and I’m looking to build my credit. I’ve been tracking it on Experian as I have 3 direct debits going out each month. I feel the next logical step would be to take out a credit card. I’ve had a look at what I would be pre-approved for but I’m not sure what one is best, they all look the same when I click on them. Would anyone be able to advise on what would be best for me and the best way to use it to build credit.
