@tinpanpv,
I suppose if none of the Ultimate edition bonuses for either appeal to you, then you will only need the standard edition. I do know that FIFA 22 was added to the EA Play (Standard, not Pro) list in June, so if you have standard EA Play and don't want to wait several months, you'll likely have to buy it, while EA Play Pro gives you immediate access.
There's a lot of options, and it's always tough knowing which one is best for you. But if you're absolutely certain that you don't want the premium editions, and don't care about all the other games included with EA Play Pro, then you probably don't want to get that, unless the early access is that valuable to you.
I hope that was clear and not just an incoherent ramble.
