Yeah, the UK, and EU are kinda lacking in some of those areas. Thankfully, I find the opposite also tends to be true. There is less broker tracking, compared to the US.
There are services where you can get a virtual card, like Barkleys, Skrill or Monzo, but they’re not temporary. Oh, you also have Revalut, but they are absolutely terrible. More like a dodgy bank substitute. I look forward to the day something like Privacy.com becomes available, in Europe.
The only service I can think of is Hushed. Though, their app is covered in trackers. For a service that advertises privacy, it doesn’t show in their app. To be fair, you can pick up a (normal carrier) PAYG SIM card, at many shops, and you don’t need to hand over your details. Just £10, for a topup, and sometimes a shop will want £1-3 for a card. Most of the time, it’s free. Less convenient than a service, but it’s more decentralised, and better for privacy.
