We perform Fisher forecasts to determine the optimal design of wide-field ground-based mm-wavelength LIM surveys for constraining properties of neutrinos and light relics. We consider measuring the auto-power spectra of several CO rotational lines (from J=2-1 to J=6-5) and the CII fine-structure line in the redshift range of $0.25<z<12$. We study the constraints with and without interloper lines as a source of noise in our analysis, and for several one- and multi-parameter extensions of $Łambda$CDM. We show that LIM surveys deployable this decade, in combination with existing CMB (primary) data, could achieve order of magnitude improvements over Planck constraints on $N_eff$ and $M_\nu$. Compared to next-generation CMB and galaxy surveys, a LIM experiment of this scale could achieve bounds that are a factor of $\sim3$ better than those forecasted for surveys such as EUCLID (galaxy clustering), and potentially exceed the constraining power of CMB-S4 by a factor of $\sim1.5$ and $\sim3$ for $N_eff$ and $M_\nu$, respectively. We show that the forecasted constraints are not substantially affected when enlarging the parameter space, and additionally demonstrate that such a survey could also be used to measure $Łambda$CDM parameters and the dark energy equation of state exquisitely well.
