Good luck. Uninstall many applications that you don't actually need. Facebook uninstall is fine because you can do the same things on Facebook online anyways and the same story for other social media.
Then some other apps you don't need can be uninstalled. If there are some apps that you need to keep, say YouTube, just clear the data in application settings which is simples. The main reason why I don't update most apps except games is because of the enormous amount of space as well as the updates happening way too often and running out of storage isn't good.
Luckily I have a large storage phone but the pains of losing storage are real. It's also easy to spend storage by taking screenshots/photos and downloading lots of musics/videos.
