  The dynamics of perfect fluid as a source in the context of modified gravity,
specifically $f(Q,T)$ gravity, are examined within the
Friedmann-Lema\^itre-Robertson-Walker (FLRW) cosmological model. This gravity
is a generic function of the non-metricity scalar $Q$ and its trace $T$. We
investigate the characteristics of the derived cosmological model using a
parameterized form of Hubble's parameter, $H(z) = H_0\left[\Omega_{0m}(1+z)^3 +
(1-\Omega_{0m})\right]^{\frac{1}{2}}$ (Mahmood et al. Int. J. Geom. Methods
Mod. Phys., https://doi.org/10.1142/S0219887824502049). Our examination reveals
how physical parameters such as energy density, pressure, and the equation of
state parameter, among others, in our model accurately describe the physical
behavior of the cosmos. Furthermore, we explore the kinematic parameters in our
model, which provide valuable insights into the cosmos's expansion history,
including its acceleration, deceleration, and the evolution of its large-scale
structure. By exploring these aspects, we gain a deeper understanding of the
cosmos's dynamics and evolution within the context of modified gravity.
