Are you familiar with the Ignore Mod Interrupt option of qmk? That solved that issue for me, depending on your typing style it might solve for you too.

Another option is moving those keys to bottom row, or moving layers to combos to free thumb keys to for mods or move mods to combos as one shots.

I just flashed one of my keyboards with the "official" ZMK layout and it's so much better. I must have missed quite a few settings when I tried replicating it myself. I can't notice the delay at all.
