I'm trying to figure out flows work with multi-select checkboxes. At this point I can only select 1 id from the list, despite the flow debug logs showing that I have selected 2. I'm aware of the documentation that says that in a Group-Checkbox that it would only capture the last id of the value that was selected.
I have been able to get the behavior that I want with a multi-select picklist but it is not as user friendly as the group checkbox option.
Essentially, I want to be able to lookup a collection of opps, have the user check the boxes for the ones they want to update, and then performa a loop on those selected opps and update them.

Consider using this Dual ListBox Flow Screen Component. Because this component expects a collection of strings for the values that get displayed, you may need to first extract the Names and ID's of your Opportunities using a couple of instances of the Extract Strings from Collections action available here.
