So Stripe picks “financial services”, and then I set up fake-stripe and I pick... “online transactions”?
Also: how does a “modern” verification marker differ from an “outdated” one? The research seems to show that users are terrible at deciding that something is unsafe based on the absence of a marking, regardless of how new and hip the marking is.
Trademarks are applicable across many named domains - the proposal is for the applicant to pick one for display purposes, however they are not limited to having a monopoly on one field of endeavor.
Short version: it would be very difficult to obtain a trademark for 'Stripe' for 'online transactions'.
As mentioned elsewhere, modern verification markers can be found on Twitter, Whatsapp, Facebook, Apple's App Store and Google Play. They are well recognized and should have interesting test results, if Google actually was interested in testing what effective verification would look like.
