It's very common for adult players to start out playing 1.e4 join ICC or similar and get absolutely pummeled for a couple months playing blitz.
Behavioral finance studies show that for adults the pain of losing is greater than the joy from winning and so what tends to happen is the adult player not used to being bad at something will seek some alternative to avoid taking the punishment.
This usually means adopting some ready made opening system so "they can just get a game"- this means the Colle, the KIA etc. They play the KID, the French, The Pirc or similar openings with a closed center so that they don't get blown out of the water in 10-15 moves.
My contention is take that same adult, slow down the time control to at least g/15 and ideally g/45 or more and really focus on playing over the classics and in a couple years they will be able to hold their own in any open game. The opening itself will matter little, because they will have a strong notion for time, material and quality.. the cornerstones of chess.
You can tell a player who has their open games down cold, they are just as dangerous in closed games because they threaten to crack it open and know what to do when it is.
just my .02 and I will leave it at that.
play what you like and enjoy the game. I just wish someone had given me this advice when I was starting out as an adult player.
