I mean the founders are able to fool Federation, Klingon, Romulan, and Cardassian sensors and scanning technology, including medical equipment. Right down to the blood cells at least. I think if ever at war with the Dominion, the Borg would simply try to completely wipe the founders out.
As for Data, I think the Borg could probably assimilate him easily if they chose to. IIRC we've seen Data interface with Starfleet technology on more than one occasion and we know they Borg can interface with it from First Contact and Voyager. What it comes down to is whether or not Data can block access to his neural net, and if the Borg can get through that firewall without taking his "brain" apart piece by piece.
I always figured that when Data said he could not be assimilated it meant the Borg couldnt assimilate him and get all of him. Sure they may be able to take control of his body but the time and effort it would take would be more than enough time for Data to completely trash his own neural network. The Queen needed those lockdown codes. If you give Data even a millisecond of time during assimilation he would delete/overwrite/delete that could a few million times so that there was no way for the Borg Queen to get the data she needed.
