I might be able to use ULAs but I have no idea how well ULAs actually work
Exactly like any other global-scope IPv6 address. They just work. (I speak
from experience.)
How do I tell my router that the ULAs on the home side of the router are
different from ULAs on the cableco side?
If you want static addresses on your servers, it's no different from any
other static address. But maybe I am not understanding your concern.
If I knew I had an address range that held still, I would use DHCPv6 and see
how many of my devices handle it. What happens if I have ULA addresses handed
out by DHCPv6 and global addresses from SLAAC? Do I have to turn off SLAAC?
(If this stuff is all written down somewhere, I would be thrilled to get
the reference.)
