Suggestions for google alternatives/foss apps

Hello everyone!

Recently, I saw so many posts about this and I started to think about degoogling (degoogleing?) my life.

I've started with fdroid and found some nice apps in there and I'm curious to know some alternatives I may or may not know

• Youtube: Currently, I use ReVanced and even though is just the default app with something in it, I want an alternative with background listening, import my subscriptions w/ notifications and if possible with sponsorblock
• Mail: Using a combo or Gmail + proton. I started to use proton recently and I want to move everything there when I have time. Suggestions here?
• Cloud storage: Self hosted/proton? Alternatives
• Gallery app: Stock
• Video player: Stock
• Music player: Stock
• 2FA app: I have Authy and I tried to install aegis. I also have Ente but I've never used both
• Mail app: Using K9 and the app is awesome compared to google or Samsung Mail
• Password Manager: Bitwarden
• Weather app: Currently, using Breezy weather

If possible, apps with a nice looking UI, modern with/without Material You

I'm using a Samsung S23 and I would like to know how bad it is to change ROM with something better and if it's really worth Pixel + GrapheneOS. Thanks

Edit: I forgot the most important one with probably no alternatives (?) Thanks to @JustMarkov@lemmy.ml (idk how to mention)
