A block suite that includes claims certainly includes custom queries for post lists and which does extend Gutenberg in two interesting ways: custom inline color and fonts.
If you need to display Custom Post Types I also would recommend you take a look at Archive Mapping and Post Selector in general or Product Blocks in the case of WooCommerce products.
This is one of may favourite block collections because it offers block management and extra display/spacing/animation settings.

Here are a few ordered from the most basic ones to those with more options/settings. I plan to add more blocks in the future as I review more block collections:
