Replying to Touring clothing/gear for a super sweaty guy

I've been touring in my resort gear, usually just wear my baselayer or insulated mid layer if its real cold on the way up. shell on the way down. my pants are decently breathable.
But now that im getting more into it, and going with some guys that move pretty quick, I really need to get my clothing dialed.
my biggest problem is i sweat a shit ton very easily, anything more than a real easy effort and ill start to sweat. I was doing some 1-2 hour efforts last year just up my local resort for training, knowing theres a lodge at the top so i didnt have to care about not sweating, and my head would be drenched, just wearing a little headband and most of my single baselayer i was wearing, a super thin merino long sleeve. and that'd happen in cold temps too where my extremities and ears and nose were freezing.
I had a couple sunset runs where on the way back down from sweating my ass of on the way up, wearing an insulator and a shell, i felt like borderline hyperthermic. kinda freaky.

I think sweating is inevitable, so i need to figure out a system that'll maintain warmth when wet, and hopefully not hold sweat and dry out super fast.

my thin merino baselayer is good for that, not much warmth but at least doesnt hold much water.

I also need a decent light shell or mid layer for when its snowing or much colder, but that needs to be breathable AF because almost no matter how cold it is, putting on anything that provides any kind of warmth will make me sweat.

I like my arteryx insulated mid layer for super easy efforts where i can avoid sweating much, that and my shell seem to provide good warmth on the way down. though im wondering if a super warm down insulator would be good instead incase i cant dry out enough and i just need max insulation.

Phew, that was a lot, any advice?
