Canon EF 100-400mmL II + EF 2x III Extender on the Canon EOS R6 camera. The EF 1.4x III and EF 2x III Extenders were redesigned "from the ground up" according to Canon. They're stronger internally and have more screws holding them together. The microprocessor inside has been updated as well as the coatings on the glass elements.

Your needs might really dictate a need for f/2.8 for your photography. Especially if you like low light photography.
1.4x III + 2x II + 2x III. I understand that the quality with stacking will deteriorate, but the 70-200mm f/2.8 II would still keep autofocus on the 1D IV with the first three combinations with 728mm FOV, and the last extreme combination would result in a crazy 1456mm on the 1D IV or 1792mm FOV on the 7D with MF.
Built for all environments. This extender boasts a coating around the outer edges of the lens elements to reduce flare. Let the lens and camera do the talking. EF Extender 1.4x III's in-built microprocessor provides accurate transfer of data from the lens and camera every time, everywhere.
