Well, you'll have to let us know if any of those varieties has less of a "chard" taste.

Chard is so ridiculously easy to grow, and it just keeps going. I've been growing it but not motivated to eat it more than once every couple of weeks. The yellow one I grew last winter was pretty mild tasting and the stalks were tender when growing in the greenhouse. Outdoors though they got tough in a hurry.

One other "substitute" I just remembered - komatsuna. Not exactly spinach but a very tender all purpose green. I mean, not tough like kale, and not chard tasting.
