Sharp and open openings for white


King's Knight's Gambit focusing on the Bc4 Kiesertitsky might be worth a thought. There's enough heavy-duty theory in, for example, John Shaw's book to satisfy many an appetite. Of course, Black has many candidate defences to the old KG but the positions rarely end up closed.

Ruy Lopez can often lead to a very positional game. If you like more aggressive openings, you can check out Scotch, Italian, or Evans Gambit for the more solid options.
But if you like wild or crazy game, you can try various gambits like King's Gambit, Vienna Gambit or Danish Gambit. However, those are considered somewhat dubious on the higher level but I think should be fine for club players.
Just play what you enjoy the most; otherwise, the options are very limited if you only follow engine's or top players' preference.
