Not happy with final product

HELP- I made a regular loaf (sandwich style) for the first time and not completely happy with the taste/density of the bread. I usually make boules and focaccia, so maybe I am used to the softness/fluffiness of that, but I want a good sandwich bread recipe. I followed Farmhouse on Boone recipe for this, but I used KA bread flour instead of AP. Should I be using AP for the sandwich loaf? Idk. I’d love any tips or a better recipe.

For this one, I made dough and kneaded until windowpane was achieved, let rise 75%, shaped into pans, doubled, and baked.
