Scanning documents into Notes

I scanned my paper mail into Evernote for years, and have recently made the switch to Apple Notes for this. But I'm still trying to come to grips with the way these scans can be added.

1. I could use the 'Scan Documents' (iOS) or 'Insert from iPhone or iPad' (macOS) feature built into Notes, which yields a document where all pages are displayed in a side-by-side widget of sorts and text in scanned documents has become searchable.
2. I could scan a document into a PDF file using a third-party application where I only see the first page of a PDF document and the text is not searchable.

I prefer using the first approach, for obvious reasons. But it becomes very tedious, when scanning documents received by mail that contain many pages. For that, I would much rather use Image Capture and the automatic document feeder built into my printer/scanner device.

I wish in macOS I could also choose 'Insert from scanner' and have it yield a side-by-side display of all scanned pages that have also become searchable. But that does not seem possible.

What other options do I have in this situation?
