Me too, but it might help to find become clear on which of the accounts you have 2FA turned on for could be reset by having them send an email, and which you would be locked out of.
The email providers I use all require 2FA, but as long as I had paper backups of recovery codes for those I could probably use those to get back into most other accounts. No comment on whether I do have aforementioned paper backups, or whether I'm just relying on having a couple of devices with access to the codes, and then hopes, prayers and obsolete e-waste in drawers...
Of course, travelling makes the puzzle even harder, and that's when it's often even more important to not get locked out of accounts. I had intended to offer a suggestion to worry less, but instead I'm going to go away and think about this more myself.
