model - Cable Parameters from Specs Data

From a 2019 specsheet for a i.e. Belden 1583A cable, I can read $Z_0=100 \pm15 \Omega $ for $f=1 \text{MHz}$, $\text{VF}=0.7$, $\text{R}=93.8 \Omega/\text{km} $, among maximum Delay, Attenuation, and others.

If I should obtain the lumped per meter R (already given), C and L parameters for a simple transmission line model, should it be correct to take?:

$$VF=\frac{1}{c \sqrt{LC}}, \ Z_0 = \sqrt{\frac{L}{C}} \\ C=\frac 1c\frac{1}{\text{VF}}\frac{1}{Z_0} ,\ L=Z_0\frac 1c \frac{1}{\text{VF}}$$

Is $VF$ in the specsheet ("Velocity Propagation Factor") indeed the Velocity Factor I am thinking?

The specified capacitances are the Non Mutual Capacitance $C_{NM}$ and the Maximum Unbalance Capacitance $C_{MU}$.

Anyway, what are the meaning of those last capacitances?
