Just a log of "my transition" and what have works well.

I used Google Maps a lot. I have moved to https://mapy.com/ works surprisingly well for navigation and regular map need, not very strong in POI, but that was expected.

Google Analytics swapped for https://dashboard.simpleanalytics.com/ - should have done this way earlier, just an overall better product for my needs.

Exited Goodreads for https://app.thestorygraph.com/ - zero problems

ChatGPT/Gemini moved to https://chat.mistral.ai/ - this one is a slight downgrade on both functionality and results. (so I am still cheating a bit on this one)

Moved to here, PieFed from Reddit - not regrets.

I was using Brave and Duckduckgo/EcoSia from before. I would consider moving away from Brave for a similar private but European browser.
