Anecdotally I think food tastes way better in general today than it did in the 80s or 90s. Avocados used to be hard and almost flavorless, strawberries were watery and less sweet, restaurants are making much more interesting and complex dishes than I remember ever seeing as a kid, and food in general even just looks better. Go back and watch some old movies with some "fancy" dinners, everything just looks disgusting, like it was all cooked in a microwave or something. The situation looks like it was even worse in the 60s and 70s.
I think the mass shipping of produce has actually gotten better, probably in no small part from logistics software. Is there a chance though that you buy groceries somewhere relatively more expensive than where you (or your parents) bought groceries in the 80s/90s? It’s still very possible to find bland strawberries, it just depends on how much you are (or aren’t) willing to pay.
Not even anecdotal, this is legitimately what occurred. Genetic engineering created better food today than even 30 years ago: https://youtube.com/watch?v=UaxzEztQcyg
