what opening should I play with white?🤔





It doesn't matter. Even if there is a difference between openings, it's very small. Play whatever you like.

"me spending most my time with black" ++ That is the right thing to do. Black is more critical than white.
As white you could open 1 a3 as @9 suggested and as Anderssen used to play, but you can also play a reverse system and try to make better use of your extra tempo than with 1 a3.
Imagine black has magically opened 0...e5 or 0...d5 and you respond to it with white as if you were black.
If you play the Sicilian Defence 1 e4 c5, then open with the English 1 c4.
If you play the Kings Indian Defence 1 d4 Nf6 2 c4 g6 3 Nc3 Bg7 as black,
then open 1 Nf3 2 g3 3 Bg2 as white.
If you play the Caro Kann 1 e4 c6 2 d4 d5 or the Slav Defence 1 d4 d5 2 c4 c6 as black,
then open with the London System 1 d4 Bf4 as white.
If you play the Dutch Defence 1 d4 f5 as black, then use the Bird Opening 1 f4 as white.
The benefit is that you do not have to put effort in your white play and the experience you gain with positions as black does double duty if you play white and the experience you gain as white does double duty it you play black.
