DeFliGra has some that are worth checking out. If you go to StacksCentral and enter ‘Grid’ in the stacks category and ‘DeFliGra’ in the developer category, you’ll see he has three worthy options.
Of course, you’ll find a wider range of options if you simply enter ‘Grid’ in the stacks category.
If you are using my Foundation stacks, the Block Grid and Column stacks inside there are very flexible. A little birdie may have told me that these could be available outside of the Foundation suite pretty soon.
