>Outside of real estate, cars, and financial products, what B2C companies do?

Declining for sure, but high ticket B2C still has salespeople.

Home improvement, cosmetic surgery, cosmetic dentistry, vocational education, timeshares, boats, recreational vehicles, insurance, furniture, solar energy, hot tubs, pool tables, pianos, etc.

And a lot of stuff at the low end, home based seller angle...beauty, vacuum cleaners, organic, supplements , diets, and so forth.
