The beauty of the only Lumix lenses I own (24-105 f4 & 70-300 f4.5-5.6) and near enough exclusively only use is both have 0.5x macro and can't help thinking how 0.5x would benefit you, unfortunately you only get 0.25x with the 70-200 f4.
Yeah macro opens your eyes to nature which you never notice, for example, I photographed tiny Rosemary lilac blue flowers to discover they looked remarkably like Orchid flowers
The spiderlings photo I got is no way visible to the eye without macro, if I crop 2x on either 0.5x macro I get equivalent full 1x, you need the same crop on 70-200 f4 to get native 0.5x
The 300mm end with 0.5x is rather excellent and my favourite for keeping distance from bees and everything else, it allows much easier working distance.
Video using APS-C mode and high stability mode on S5ii gets you beyond 1x macro using up to c4k!
The O.I.S is brilliant all these Lumix zooms have.
