Fluid changes look good. Others look good to me too (that is pretty old eslint deps).
You could adjust samples packages to use ^2.40 (or higher) for samples. You only need to use a range if the package imports from /legacy or /beta. Assuming package manager resolves all of the things well, using ^ might simplify you updates (less files to touch).
