You can use/host searx (https://searx.space/) or yacy (https://yacy.net/) to go one step further.
Somewhere in between, Google stopped caring, and we have what we have today.
Dark mode to save my eyes, setting my own personal preferences for which search engines to use for results, Cached results link and proxied links, a files search engine...
The only difference is that I wasn't already heavily invested in other Google products. e.g. Gmail, Lots of saved Maps POI, etc.
For someone who is heavily invested, I'm not sure if the switch to Searx is worth the lack of convenience.
