I need some advice on repairing a concrete floor in my basement after a plumber dug it up for drain lines. My plan is to use the broken concrete pieces as backfill after I break them into smaller chunks, then add gravel where needed before pouring new concrete. Is this a solid approach? Also, should I incorporate rebar for added support?

It looks like a pretty big job! You might need a truck to deliver that much concrete. While I totally get wanting to save money, I’d recommend having a pro handle it unless you’re confident in your skills. Costs are through the roof these days, but mistakes can be even pricier!
Those pictures suggest the pipe might not have enough concrete coverage on top, which could lead to it breaking under weight. Your plan sounds okay, but make sure to tamp that gravel properly before pouring. Aim for about 4 inches of concrete for a strong floor.
Is that pipe even below the floor level? You might have had a much easier time just removing the broken concrete before the drainage was put in place.
It's just slightly under the floor. The drain needs to be graded, and the main sewer line it ties into is pretty shallow.
The angle of the photo isn't misleading. The pipe was laid shallow due to grade issues and its location in relation to the main line.
