How did the Empire consolidating it's powers at least throughout the 14-year gap after Revenge of the Sith and Andor?

For an example, we know through the deleted scenes from Revenge of the Sith mainly the ones with the delegation of 2,000 Bail Organa mentions now that Palpatine has control over the Jedi Council he made a decree called The Sector Governance Decree which was a proclamation passed by Supreme Chancellor Palpatine himself via his emergency powers. As the name implied, it gave Palpatine the power to install a new system of sectorial governorship, giving those governors power within the sectors they were assigned.

But I'm curious on how besides that and the birth of the empire in general how did the Empire consolidated it's power over the course of 14 years leading to Andor and even during it such as the PORD.

Now I'm aware about the Reconquest of the Rim which was about the Empire finishing off Separatists Holdouts or attacking planets on Separatist alleged or have separatist views which resulted in events such as The Antar Atrocity by Tarkin and The Western Reaches pacification operations also by Tarkin.

By the time we reach Andor which is around 5 BBY, The Imperial Senate is weakened and it's influence eroded, you have the Empire using private companies like the Preox Morlana to take over planets such as Ferrix before Cassian killed those two cops, and then you have the Empire cutting off shipping lanes from Ghorman, as well as the different rebel factions such as Saw Gerrera's Partisans, Anto Kreegyr's Separatist holdout, Luthen Rael's Network, Maya Pei's Neo-Republicans, The Ghorman Front, The Partisan Alliance, The Sectorists, Human Cultists, and Galaxy Partitionists.
