I've been on this path for years, with varying degrees if faulure. How did you manage it?
Some bits are harder than others.
Most of my important email was migrated to a Protonmail account. With the exception with a couple of things tied to government services that don't have a path of changing your email, which sucks.
Android: Next time I switch devices I am going for GrapheneOS. Technically still an Android, sandboxed Google services and all, but a step in a better direction.
Android Auto/Waze: There's no competition here, sadly.
YouTube: Another thing that is very difficult to replace beyond just reducing my YouTube usage. I can use stuff as Newpipe or self host Invidious, but technically it is still YouTube.
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.
There’s a platform called Odysee which hosts mirrors of many YouTube channels, might want to check that out instead of alternative frontends like invidious.
I ungoogled when google locked my account many years ago (I didn't see hundreds posts about it). I don't use youtube, what do you need it for? FOMO? Internets are not monopolized enough yet for google to obscure them.
for youtube i use ytdl (very easy to install with pip or w/e new thing there is now). then at least it's more of a deliberate choice to watch something rather than random thrill seeking.
