Most weather and climate datasets - including ERA5 - are highly structured on regular latitude-longitude grids. Even if you were solely doing timeseries analyses for specific locations plucked from this grid, the strength of this sort of dataset is its intrinsic spatiotemporal structure and context, and it makes very little sense to completely destroy the dataset's structure unless you were solely and exclusively to extract point timeseries. And even then, you'd probably want to decimate the data pretty dramatically, since there is very little use case for, say, a point timeseries of surface temperature in the middle of the ocean!
The vast majority of research and operational applications of datasets like ERA5 are probably better suited by leveraging cloud-optimized replicas of the original dataset, such as ARCO-ERA5 published on the Google Public Datasets program [1]. These versions of the dataset preserve the original structure, and chunk it in ways that are amenable to massively parallel access via cloud storage. In almost any case I've encountered in my career, a generically chunked Zarr-based archive of a dataset like this will be more than performant enough for the majority of use cases that one might care about.
