I’m going to be running the h9 in the es8 obviously, but my question is should I get the SP-H9 and use it to directly control the h9, or should I get the SP1-RB and plug it into the exp ctrl1 inputs on the es8?
I waited to see if any ES8 users would comment because I don't have a clear answer for you. The Boss ES8 manual does not state that it allows both an auxiliary switch and auxiliary button to be used in tandem, so your best option is to either connect an SP-H9 directly to your H9 or use it simply as an expression pedal. The H9 has a specific mode that allows users to use the expression pedal in conjunction with a one-button aux switch, but as far as I can tell, this mode cannot be replicated using ONE control input on the ES8.

..will I be able to assign the toe switch to the hotswitch on the h9? Thanks in advance for your help and patience!
The toe switch on the SP-H9 can be assigned to any function a normal aux switch can be assigned to. In H9 Control, under the PEDAL tab, then Aux Switch Mappings, you'll find the complete list of assignable functions.
