The truth is single-use plastics are very useful in certain applications. Sanitation and reducing food waste likely outweigh the cost. I do think it's great we're being more thoughtful in our consumption and thinking more about where stuff goes when we throw it "away."
I do think you can address some of your issues assuming your grocer is a bit accommodating and you don't mind the perception of being a bit odd. Farmer's Markets rarely package things like grapes and cherry tomatoes. I got some reusable produce bags that have a tare weight written on them [1] (I don't usually bother having them tare it). I just stuff the produce bags into one of my grocery bags.
There are a bunch of "zero-waste blogs." I can't seem to find it, but I remember watching one video bio where she went grocery shopping. She had them put cuts of meat into jars and brought her own containers for everything. The only "waste" was the paper sticker they put on her jar. She did say it was a bit odd at first and she had built a relationship with the grocer, but I'm pretty sure it was just a local Whole Foods.
