Also mixed success, but it depends what you want to achieve. My goal was to minimise risk of life disruption, and I think I succeeded. Some people are on a quest to keep their lives private, and that is harder.
Email: The most important component here is owning your domain. Then you can switch between providers. I'm using iCloud now because I can have email addresses for the whole family for very cheap and it integrates well with my Apple devices.
Search: Kagi.
Maps: I still use Google maps. The alternatives are just not as good here in Denmark.
Phone: iOS. I really want to try GrapheneOS but our government uses a national ID app which only works on official Android and iOS builds. It's very annoying to function without that app.
YouTube: Still use it as well, but with ad and sponsor blocks on computer and mobile. I have an Apple developer account and sign my own sideloaded YouTube apps.
Cloud storage: I switched to iCloud, but I keep a full local copy of everything in case I lose access to my account. I also built a home NAS and keep the movies on that. Basically anything which I don't mind losing so much.
Docs: I use Office applications primarily now instead of Google Docs.
My main concern was actually being locked off my Google account once I realized how much of a wrench it would throw into my life if that happened. Privacy is a secondary concern here - not that I don't think it matters, more that I think it's a lot trickier than simply avoiding Google services.
I recently acquired my own domain, and perhaps that is a good idea, especially considering I can set it up on Proton too.
For Maps I tried HERE and TomTom, but they simply are not good enough where I live (in Europe, ironically). HERE doesn't know that some streets exist on my town, TomTom is missing a lot of addresses which makes things very cumbersome super quickly.
Phone: Apple is not an option. I despise Apple products, and I don't think they are any better than Google.
Cloud storage: I've switched to self hosting + tailscale here. It has been working actually pretty well.
