Act 1 is a chore to get through on replay.
Good news is if you have the DLC you can skip the first act. The DLC start puts you in front of the Church in Pacifica after fighting Placide.
I like Cyberpunk a lot but replayability is shallow like you say. Sometimes I just boot it up to punch npcs though. Make a gorilla arms build and go ham. It's pretty cathartic.
Fuck.
