The near field versus far field for a photon is very interesting and quite complex as you so aptly show and the Wiki pic also shows. At long radio wavelengths, single photons are quite large but radio waves usually come from a coherent motion of electrons in a macroscopic antenna. So the near field is a superposition of a very large number of electron fields and therefore photons and the antenna radiation is not yet "free". In the far field, the antenna becomes a point source and the waves then coherent and dipolar.
The near field is simply affected by multipoles and not yet a dipole field.
It is better to focus on a nice radiowave like the hydrogen atom 21 cm line at 1.4 GHz. This is a spin-flip transition that is highly forbidden and has a 10 million year half-life. How can such a large 21 cm single photon come from such a tini-tiny hydrogen atom 0.1 nm and yet the radiowave comes from 4.8e-9 size electron cloud.
The near field for a hydrogen is now defined relative to the size of the hydrogen atom and there are also multipolar effects for this near field. This transition can be observed as part of a maser and so the near field can actually be measured in a hydrogen maser.
Gravity is due to the far field effects of single photons, so once again, the far field gets us back to graviton noise. Graviton noise is the noise of ground-state atom oscillations ever since CMB creation...Attachment #1: nearFieldFarField.JPG
