Index list - show the last person who edited each page

Flowlynow you won't be able to do this with SharePoint alone, you'll need a flow in Power Automate. That can save the Modified By details into the list. But getting the info about who did the most recent comment is a lot more difficult because the comments are saved in the schema of the list, not in a list,  library or column. Even with a send an http request to SharePoint action I think you'll struggle because it can get the first comment and, in theory, replies (although I've never got that to work successfully). But it can't get who made the comment or when.
