Apply the IE GPOs to all Windows 10 and Server systems;

Apply anything with "Windows 10" in the name to Windows 10 systems;

Apply anything with "Member Server" in the name to Member servers and to standalone Server systems;

Apply anything with "Domain Controller" in the name to DCs;

Apply anything else with "Server" in the name to Server systems (including DCs, Members, or standalone).

Precedence order between these policies won't matter because there aren't any conflicting settings.
