"Grid Masonry" is one of the Dynamic Posts render types where a grid layout library is shown. It works by placing elements in a position based on the available vertical space.
You can enable:
Show filters, that allow showing a filter above the grid so you can view only the filtered post. On filters, you can choose:
if you want to show only all first-level terms;
if you want to add ACF as data filters;
change the "All" word;
the separator of each term;
the alignment of the filter;
if you want to show/hide the empty terms;
Use the years above the block.
