The OS name isn't needed any longer.

Suggestion:
"Noto Sans Myanmar");
private static final String FONT_NAME = selectFontName();
A blank line.

Suggestion:
throw new SkippedException("No suitable font found out of the list:
"
+ String.join(", ", FONT_CANDIDATES));

I'm for preserving the original wrapping style where `.` align:
Suggestion:
return Arrays.stream(GraphicsEnvironment
.getLocalGraphicsEnvironment()
.getAvailableFontFamilyNames())
.filter(FONT_CANDIDATES::contains)
.findFirst()
.orElse(null);
