+1 for SingleFile

I recently tried LinkWarden, Linkding and Archivebox for making offline copies. They all had the same issue of running in to a Captcha or login wall for the sites I wanted to capture.
SingleFile to the rescue, as it uses your current browser session as a logged in and verified human.

Linkeding allows you to upload the singlefile html file attached to it link, but I didn’t see such an option for Linkwarden.
