Should be in core WP

Does exactly what it says and is very helpful in managing large file assets. Clean and easy to use, as well as fast and responsive.

The gallery block that is included is nice, but could have some simple tweaks to make it even better (select media size for images, plus an out-of-the-box lightbox, but it does play very nicely with WP Featherlight).

Support might be the best thing about it though. They were very quick, responsive, and helpful. Definitely recommend.
