Does the new ISP require use of their router or just offer it as an option?
AT&T used to require using their router, which was a pile of hot garbage. I have a Mikrotik Router and managed to mostly cut the AT&T router out but I had to configure my router to use the AT&T router for authentication, at which point the Mikrotik would take over. It was complicated to configure but it worked.
After a quick glance at the demo, I think the UI design is better than Paperless-ngx (at least on mobile). But, it only has tags. Not correspondents and document types. It also lacks the automatic matching feature, advanced search filters, custom fields, and customizable document views that Paperless has.
