going to grow them in less intense (later in the day) direct sunlight for probably only 4-7 hours of direct mid-day to late-day direct sun. can someone let me know how they might do in those light conditions?

Not nearly as well. Tomatoes, regardless of the variety, require 6-8 hours of direct sunlight for best results. Less hours and/or less intensity results in lanky/leggy plants with reduced production and more inclination toward disease and pest problems.

Tomatoes need six to eight hours of light, so be sure to put your containers in sunny locations, and if need be, move them as the sun changes position.

I'm new here so I don't know if my location is easy to determine... it's Chicago. I've grown San Marzano Redorta (seeds from Italy) for two years and have given my extra seedlings to neighbors. We've all experienced the same thing: plentiful large tomatoes that refuse to ripen (for months they just hang there green, not growing larger, but showing no color or coloring in small blotches).
