Howdy,
fellow Northerner here. Not quite Canada, but near the border. Same situation: well water, septic, in the middle of the woods.
I’m planning an upgrade a bit smaller than yours, adding a 300 gal.
Have you thought about a drip system? That would spread out the water purge into your septic, but it would make disposal with a hose difficult. I’ve had my sub-slab drainage pipe freeze up at the end in the field out back by draining my dehumidifier into it in the basement…rookie mistake.

do you have thoughts/ideas about solutions for the continuous discharge from a drip system?

is there a difference between the periodic high volume discharge of manual water changed vs the constant low volume flow from a drip system (any different than a running toilet?)

I hope you don’t take this as highjacking your thread, just adding thoughts. I had a drip system at my old house and I personally find it to be a lifesaver on larger setups and multiple tanks. Maybe something to consider while you plan your expansion.
Peace
