What is the most accepted trans masc flag?

Hey y'all I am making a wallpapers for my community and one of the ones I wanna make is a series for trans people. A "all [blank] are [blank]"

So like "All women are women" and "All men are men" and then "All enbies are enbies" (Not 100% sure on the non-binary one, but I'm still work shopping it. Open to suggestions)

I wanna make the background the masculine flag, but when I looked it up there were like 4 of them, so I figured I might as well pool and ask what you all think is the most common/we'll recognized masc flag?
