WordPress theme development using ACF

Hi!

I am currently building custom themes using ACF Pro blocks, considering it is much quicker than using React, even though I am quite good with React.

I build mostly all of the theme as custom blocks, since they are designed in Figma. For example, text section, FAQ, post listing, and others.

I appreciate my theme is not extremely customisable by the user, however it ensures design consistency agreed with the client, and very light.

I am wondering, is this one of the best ways forward? How are you building themes which have very specific designs? Consistency is my biggest blocker to use core blocks. For example, I cannot influence mobile breakpoints, accessible markup sometimes, and similar.

Thank you!
