  Graphene-based van der Waals heterostructures take advantage of tailoring
spin-orbit coupling (SOC) in the graphene layer by proximity effect. At
long-wavelength -- saddled by the electronic states near the Dirac points --
the proximitized features can be effectively modelled by the Hamiltonian
involving novel SOC terms and allow for an admixture of the tangential and
radial spin textures -- by the so-called Rashba angle $\theta_{\text{R}}$.
Taking such effective models we perform realistic large-scale magneto-transport
calculations -- transverse magnetic focusing and Dyakonov-Perel spin relaxation
-- and show that there are unique qualitative and quantitative features
allowing for an unbiased experimental disentanglement of the conventional
Rashba SOC from its novel radial counterpart, called here the radial Rashba
SOC. Along with that, we propose a scheme for a direct estimation of the Rashba
angle by exploring the magneto-response symmetries when swapping an in-plane
magnetic field. To complete the story, we analyze the magneto-transport
signatures in the presence of an emergent Dresselhaus SOC and also provide some
generic ramifications about possible scenarios of the radial superconducting
diode effect.
