Does the Metamagic Adept feat gives access to Flexible Casting as well or just sorcery points when taken at 1st level as a Variant Human Sorcerer?

Question

Build

Race: Variant Human (feat: Metamagic Adept)

Class: Sorcerer (Shadow)

Metamagic adept feat:

(...)You gain 2 sorcery points to spend on Metamagic (these points are added to any sorcery points you have from another source but can be used only on Metamagic). You regain all spent sorcery points when you finish a long rest.

So I gain 2 sorcery points that I can use only on metamagic.

Examples: Subtle spell 2 times or Quickened spell one time.

Then after doing that: my sorcery points are now at 0

Can I then use spell points (or spell slots if you don't use this variant) to simply regain 1-2 sorcery points?

Sidenote

Just by curiosity, if the above is allowed and there are other uses because of a racial ability or variant somewhere, can the newly acquired sorcery points be used for anything else than metamagic? (I'm assuming there might be such an ability somewhere)
