I mostly play Rapid (currently 810 on chess.com, 1300 on lichess), my blitz elo’s in the 500s because 99% of the time when I play with 3 mins I lose on time and/or immediately hang my queen lol.
I almost always play the King’s Pawn, and when playing black I always respond to 1. e4 e5 2. Nf3 with either 4 Knights Game or the French. And when I’m White and don’t play that opening, I play the Spanish Game followed by doubling their pawns and then o-o.
I sort of know the Catalan but it’s a bit too passive for my liking (often starts with g3) and I myself know how to punish it as Black
For whatever my opinion is worth (I'm ~1350 blitz on lichess), if you're finding your openings boring, then just try something new. For me, it helps to keep in mind that the goal is to have fun, NOT to maintain a certain Elo.
