I've been using duckduckgo for half a year already they've became quite good compared to Google search, Google maps alternative is any popular maps app just try what'll fit your tastes, but YouTube is certainly don't have alternatives YET just because libre alternatives though exist but not yet in shape enough (basically we need datahoarders who'll hoard and host whole youtube to libre alternatives such as framatube and others) for now we can only rely to custom frontends such as clipious, piped and others and custom apps of course

I started ditching google apps last spring and my “alternatives” are: bing/apple maps, invidious, and SearXNG. I self-host the last two to keep even more control of my data.

there is no such "better" alternative. how could we compare a company that has been digging up their user data and built something with it, vs some community or even a solo developer who build something out of nowhere without collecting or selling data?

but, what are the alternative?

Google Maps

• OpenStreetMap, is not as complete as Google Map, the amount of places won't be the same. but it's enough to help you navigating from a district to another district, and use much lower resource too

YouTube

• Odysee, couldn't explain, think of it like YouTube
• Rumble, couldn't explain, think of it like YouTube
• PeerTube, a fediverse software where you can upload videos and do livestream, you own your data
• Piped, NewPipe, PipePipe, Invidious are just alternative frontend for YouTube, its good if you are watching an exclusive content from their platform. But why do we keep letting YouTube has our data?

Google Search

wow, really?

1. DuckDuckGo, controversial, but enough
2. Brave Search, controversial, honestly aint using it
3. Searx, host it yourself, you own your data

and hey, why didn't you mention about the browser, mails, and many more? There is firefox, tuta, and much more.

OpenStreetMap instead of Google Maps (OSM would be even better if more people used and actively contributed mapping data to it), no real youtube alternative yet (but see Piped/Invidious, Peertube, and Odysee), and there's plenty of alternative search engines like Duckduckgo, Brave search (has its own index), etc
