Wire 2 separate lights from a dedicated outlet plug
You can't pull from the microwave circuit under Code, so use the range hood circuit instead
Your 1700W microwave is far in excess of the 50% limit set by NEC 210.23(B)(2) on the total wattage of fixed appliances connected to branch circuits that also have lighting and/or general-use receptacles on them:

(2) Utilization Equipment Fastened in Place. The total rating
of utilization equipment fastened in place, other than luminaires, shall not exceed 50 percent of the branch-circuit ampere
rating where lighting units, cord-and-plug-connected utilization
equipment not fastened in place, or both, are also supplied.

As a result, attaching your switches to the microwave branch circuit is no good.  However, since your range hood pulls far less than the 10A/1200W maximum NEC 210.23(B)(2) sets for a built-in/fixed appliance on a general circuit, running the lighting off the range hood circuit will be fine, barring any local amendment that requires a dedicated circuit for the range hood (which sounds strange, but does exist in a few places in California).
