I think xyz2grd should go under "operations on tabular data" rather than "operations on grids" in doc/api/index.rst.

Looks good! Just three suggestions - two for adding missing lower-case common options and one for referring to an alias rather than short option.

Looks fine to me!

When I run make check it gives me a bunch of errors for invalid escape sequences; is there anyway to disable this for the style checks?

One suggestion to add alias for projection -J, but still missing aliases for -D/-S/-Z from https://docs.generic-mapping-tools.org/6.2/xyz2grd. If you're not adding those 3 (which is fine if you're in a rush to get this merged before v0.5.0), then please edit the first post to change "Fixes #1424" to "Addresses #1424".
