I don't like how modern "Flag Officers" or "Admiralty" still wears pips with a Trapezoid surrounding it to show that they're above the regular Rank & File crew when they're shown on ST:Picard and ST:Prodigy in the late 24th / early 25th century.Well, I wouldn't say absolutely nothing. I think much of the confusion stems from TNG season 1 where admirals wore a weird rank braid insignia.
We've seen Quinn and Jameson with just the braid, Savar with the braid and one pip beneath, and Aaron with braid and two pips.
Since arguably just the braid should logically be the lowest admiralty rank and Quinn and Jameson were addressed as admiral, the implication seems to be that the one star rank wasn't called Commodore during that time.

I thing "Flag Officers" should be wearing the standard 5-Point Star instead of circular Pips.
Mount the 5-Point Stars on a single piece Rank Badge and call it a day.
You can do something fancy with the 5-Point Star and have the StarFleet Arrow-head hidden within the points of the Star and all pointing outwards.
Instead of frilly accents on the edges of the uniform, just give the flag officers a simple "Cape" to distinguish them from regular "Field Officers" & "Line Officers".
