I'm not entirely sure I understand the question.
You already seem to have the buzzwords necessary to land a reasonable position.

This is a light time for hiring, as you state: lots of people are on vacation.
While people do look for specific buzzwords, the better ones realize that you can teach anybody a framework and it's among the less-important aspects of the hiring process. I see a pretty even mix of Angular vs. React jobs these days. I have neither on my resume (but have been doing React for some time now) and get more requests for Angular than React--but that might also be because it's harder to find Angular devs.
In my experience there's nothing about a startup failure that indicates a candidate isn't suited for a development position.
