Some alternatives you could try:

• Search: Brave search / kagi search
• Mail: Protonmail
• Drive: filen / Proton drive
• Maps: openstreetmap (there are multiple applications integrating it)
• TOTP: Aegis (android)
• Android: LineageOS
• (Or self hosting, which can replace google services)

These are the things that just quickly came to mind, hope it helps :)
