We quickly ran into the same issue at Shopify. We've since moved from a flat list into sections by "domains"; within each section is the breakdown by type. You can see it here: https://shopify.dev/docs/admin-api/graphql/reference

Of course this grouping has to be done a little manually. And it's not perfect, but definitely better than the flat alternative. For reference, we have thousands of types.

I could see us adding support for grouping via the "metadata" that would inform the nav bar on how to group and accordion / collapse things. There already is a pattern for grouping in the library that is exemplified in the Query and Mutation carats
