How many of these items does the electrician put in?
I know this is primarily opinion based but IMO it's appropriate for the site.

Here is my take: (mine in bold)

a. put in the orange tube for running future technology wires? Not standard procedure, but certainly a job for the electrician at added cost.

b. wire for cat 6 Ethernet cabling for hard wire computer connections? Not standard procedure for many, but certainly a job for the electrician at added cost. This is standard for me.

c. wire for coaxial for internet and cable? For me this is standard procedure.

d. wire for security camera? Not standard procedure, but certainly a job for the electrician at added cost.

e. wire for security system (creating your own, not using a security company). Not standard procedure, but certainly a job for the electrician at added cost.

f. wire the electrical portion of the furnace? Typically the electrician's job.

g. wire for 2 zones for the heating? If you mean the control wiring for me it's a toss up. Both HVAC contractors and electrician will do this.

h. install the venting for the bath fans? Typically the electrician, but some will leave it for the GC Or HVAC.

i. install over stove microwave/vented fan and do the venting? Typically the circuit and receptacle are the electrician. Installation and venting are GC.
