What should I upgrade next?

Hi, everyone! I just got a job, and recently, my laptop died. I had to rush to buy a PC (mainly used for browsing, watching movies, photo/video editing, and very light gaming). Here are the specs I was able to get:

- AMD Ryzen 5 5500 Socket Am4 3.6GHz Processor with AMD wraith cooler

- Gigabyte B550M-K Socket Am4 Ddr4 Motherboard

- HKC PC 16gb 3200mhz DDR4 with Heatsink Memory Black

- Biostar Rx 580 VA5815RQ82 Dual Cooling Fan 8gb 256bit GDdr5 Gaming

- ESGaming 512GB SATA 2.5 Solid State Drive

- Acer AC-500 500W Non-Modular 80+ Bronze Power Supply Black

- InPlay Openview V540 Built-in 4RGB Fans Micro ATX PC Case Black

What should I upgrade next? What should I earn for? No constraints with the budget, but I'm really just aiming for a mid-range build. Btw, I'm also a newbie when it comes to hardware.
