I work at Temporal[1], where we solve a bunch of these problems for you by cleanly abstracting the critical event sourcing bits under our SDKs. I think everyone who tries event sourcing eventually rolls their own framework or takes one of the shelf, and Temporal is the most battle tested one I've ever found.

The reason I posted this was that I found it helpful in prepping for a workshop I was giving today - recording is not up yet but slides are here https://docs.google.com/presentation/d/1mAPYXNmRdDKepXylB91F...
