Depending how many windows you have open during editing, you could increase to 32 GB of RAM. Generally 16 GB is enough for general use but not knowing how intensive your editing, etc. may be 32 GB would be future proofing the system.  And also go up to and including a 2 TB M.2 SSD. Crucial has examples of those components here.
What upgrade advice would you give for this laptop in order to increase performance and also can increase the storage space? specifically, the SSD which is where I have all program files stored and it keeps filling up. Can I upgrade to a larger SSD?  I mainly use the laptop for college stuff. sometimes video editing with adobe products. web browser. etc... I run 3D Mark since this is a gaming laptop and I got, Time spy score  2096, Graphics 2036, and CPU 2522. Let me know if you need to run some other tests and what apps to use to get an idea of the laptop's current performance.  The current specifications of the laptop are as follows, let me know if need more details.
