It is unclear whether or not aria label should be supported in this case:

Note: aria-label is intended for use on interactive elements, or elements made to be interactive via other ARIA declarations, when there is no appropriate text visible in the DOM that could be referenced as a label

https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA/Attributes/aria-label

https://w3c.github.io/aria/#aria-label

Should aria label be supported on all elements? Is an explicit specification needed to determine which elements to support?

ARIA 1.2 doesn't list aria-label as a supported property on role="cell" or role="gridcell" components, which are the equivalent of the HTML td element. Additionally, the strong role, which is the equivalent of the HTML strong element, is prohibited from having an aria-label element. This is true all "generic" elements (including span).

Thanks @fstrr, closing this as invalid

While it's true it's not listed as a supported property for role="cell" it is however under inherited properties which are described as being part of the full set of supported properties. In fact cell and gridcell and many other elements are listed under section 5.2.8.4 Roles Supporting Name from Author, which explicitly states that those elements support aria-label. Furthermore I tested voiceover and narrator, which both read aria-label on e.g role=cell.
