Recently I put an ironman 4x4 bumper/grill guard on my 2023 stx 4x4 and and now my unwanted yet tolerable rake has become unbearable. Does anyone have any previous experience leveling the front end with an estimated 340ish extra pounds on the front end?

I believe I'd research what springs you already have, cross reference with suppliers like Fox, HaloLift, Icon, and others, and get the next step up spring rating on a set of coilovers.
If you go the beerstain route, that would be another good time to upgrade the springs. You're already into the labor intensive setup, like having to disassemble the front struts, so just replace your original springs the next step up. YMMD
