Surely you mean ascending!

Preserves > marmalade & jam > jelly

I want maximal fruit flavor for combination with my peanut butter.

Which makes me consider other options. Peanut butter and banana is a classic, ofc, but should I try even-more-concentrated fruits? Fruit jerky? Dried mangos? But then the texture would be weird; probably have to chop up the dried fruit, first. Or what about making a fruit-based tea, then using that as the water for making the bread?

Or, hell, we could subvert the entire PB&J structure. Use strawberry fruit jerky as the "bread", and PB + ... banana? as the filling. (Considered various "bread" fillings, like crushed Ritz crackers. I dunno, I'd try it. Strawberry jerky, with a little peanut butter and crushed ritz crackers in between)
