I order my declarations and have for years. Like many personalized code styles, it's much easier to maintain on a codebase you fly solo in.

My ordering is by my mental model of "impact" of the declaration. Generally: Display -> Position -> Box Model -> Text/Font -> Background -> Misc.

  /* Example from css file i have open */
  .officeBlock .email {
    display: inline-block;
    padding: 14px 10px 8px;
    background-color: #E0EFFE;
    border-radius: 50%;
    transition: 0.25s ease-out;
  }

Subjectively it's helpful for quickly understanding style blocks, particularly complex ones. Is the time investment a net positive? Possibly. I'd suggest it is worth trying on a project to see if it helps when you return to it months later, at least.
