My instructions were more restrictive than yours - basically low fiber foods three and two days before the procedure and then no solids the day before. I typically eat a ton of fruit (and some veggies) so that was the hardest part of the prep for me lol.
If I were you, I’d err on the side of lower fiber food, not just no berries or nuts, but that’s just me. Sucky as that prep was, the last thing you want is to have to do it again because you’re not cleaned out enough. A few weeks before my procedure there was a poster here on DCUM who didn’t get cleaned out and had to either redo it or come back in a year, that motivated me.
Good luck, hope it goes well.
