Linux scanner support is amazing. I have a >10 year old printer/scanner/fax machine that I still use for scanning and faxing sometimes. Getting scanning to work in modern MacOS or Windows is ... an adventure. It's possible! But an adventure for sure.

I was delighted when I opened the scanner tool in fedora/gnome for laughs and it showed the (networked) machine as a scanning source. And I selected it. AND IT WORKED. I never even had to set it up!

In general, if there aren't Image Capture drivers, then older, largely 32-bit scan software won't work on Catalina or newer. It's kind of a gamble, and you sometimes have to manually run the device file from the image capture directory to get it to properly load the driver.

I remember the only challenge getting my TMA flatbed scanner working with Ubuntu Studio in 2010 was downloading an extra xsane package.
