To be honest Figma gives plenty of tools to solve this problem. With various reusable components, font/color/sizing templates etc. Its reasonably easy to be extremely consistent with your measurements in figma, as long as designers spend the time to learn the tool, and not just use it like photoshop / illustrator.

Even resizability can be done quite well, allowing the designers to create reusable bits that stretch and squeeze to fit the needed space, and the way they deformed can be easily read (and verified!)
