Fields proper organization and layout

Hi, I want to ask about how to better organize the fields in a regular controller (fields in the models fields.yaml file).
I´d like the fields to “flow” better, for example notice in the attached picture that there’s some akward spacing between the excertp and content fields. I’d like them to stay together one above each other. The problem is that I have fields with different height in the right column. I could always solve that changing the order of the fields and alternate between right and left, but that absolutely breaks the proper order when using a mobile phone where only one column is present.

I’d really like to have first all the fields in the left and then the ones in the right… and have them flow naturally.
