You don't really have that choice. Many social apps (Facebook, Instagram, Twitter) aren't possible to uninstall unless you use a custom ROM. You can only "disable" the apps.
It's still perfectly possible to just not open them/log in, obviously.

This isn't a problem if you have a rooted device, but root is difficult/impossible to obtain on certain devices (like Samsung's Galaxy 8 onward) due to enterprise level tamper-proofing.
Having said all that, I just got an unlocked Pixel 4 and it has zero of that bloat. If you happen to consider the Google services themselves bloat/tracking (they often are), rooting is fully supported which allows you to install an Android distribution without any Google services.
Typically, "uninstallable" apps can be disabled via adb commands if you don't want to (or can't) flash a custom ROM. Sometimes they can't however - for example, Amazon sells subsidized phones that display advertisements on the lock screen.
