Finding good royalty free photos/music/sounds?

I was just wondering if any developers here could point me out to some great sites for finding royalty free photos for creating my own textures? I’m talking about photos of wood/metal/ecs surfaces with even lighting and good quality?

I’m also wondering if anyone has any experience with any sound/music sites that are royalty free that they would recommend.

I’m looking for good, affordable, royalty free content that can be used as assets in a commercial indie game, from known legitimate sites.

Those are good sites:

textures: https://freestocktextures/
sound: https://freesound.org/
