Where would you put storage cabinets in this large open basement?

Large open basement. These were listing photos but it’s the actual basement and we have it laid out similarly with a large U-shaped sectional where the couch is and a wall mounted TV instead of the entertainment center. I’m thinking cabinets in the mid section of the wall to the right of the TV in the first picture. Will be using that half of the basement as a play area for kids and need storage for toys/whatnot.

Looking at the IKEA cabinets included in pics as well. Thinking 4-5 base cabinets bookended w the taller standing ones on both ends. I don’t think the cabinets should run the entire length of that section on the wall, but open to feedback. I don’t have any interior design background so what do know😬

Also open to other cabinet suggestions. TIA!
