From the list of virtues, which one was this signaling?

https://www.virtuesforlife.com/virtues-list/

I’d guess: Respect, consideration, authenticity, fairness.

Or should I too perhaps wait for OP to respond.

That list needs updating. Lots of things became virtuous in scenario. During Covid, fear was a virtue. You had to prove how scared you were of it, all the masks you wore because it made you “one of the good ones” to be fearful.
