I would concur that all I mostly need is CSS modules and to know when styles should be copied (most of the time) or actual utilities (rare).

Any remaining reusability can be handled with templates / components (depends on your framework).

The remaining potentially nice thing about Tailwind is that it more naturally constrains your options/syntax with utilities - when working with designers, this is probably a good thing. As always, the hardest problem of development is finding technology that best establishes the social contract.
