I have a plow for my 4Runner.

I just plowed my street this week with about a foot of new snow.
But I don't use chains. It depends on where you are and how much ice you get probably. I owned a commercial snow plow company in Montana for a number of years. I never put chains on any of my plow vehicles either. Snow tires work well enough we never needed chains except on equipment like the tractors that have hard rubber for agricultural use.
4runner certainly isn't what I'd choose for a commercial plow rig. Heavy and short wheel base are big positives. But the front steering isn't really up to the task of hanging 500lbs off the front and beating on it. I think you'd be replacing steering racks every season. And rear visibility sucks. I only do my 100 feet of driveway a few times a year and when we get a big dump of a foot of snow I'll go plow all my neighbors who hand shovel or use ATVs that can't manage the deeper snow because my 2yr old loves to go plowing. Haha.
I think the traditional recommendation of front chains was for trucks with most of the weight up front and having them on the steering axle. Probably makes sense, especially on something like a diesel truck that might have 60-70% weight forward. On a roughly 50/50 SUV, going on the rear tires is probably about the same performance. I do think you could get away with low profile cables up front, but it'll be close on the bumper and fender clearance even if the brake and abs lines aren't a problem.
