The standard model (in theoretical physics) for the observable universe on the largest length scales of cosmology:
it is an inflationary FRW spacetime with cosmological constant (“dark energy”) and cold dark matter. The technical term for this is the $\Lambda$ CDM concordance model (where “$\Lambda$” is the standard symbol for the cosmological constant and “CDM” is for “cold dark matter”).
The current model assumes that the energy density of the observable universe consists of
26.8% dark matter
68.3% dark energy.
(e.g. Einasto 09, fig 17, here)
The renormalization freedom in perturbative quantization of gravity (perturbative quantum gravity) induces freedom in the choice of vacuum expectation value of the stressenergy tensor and hence in the cosmological constant.
For review see Hack 15, section 3.2.1
