Create form with multiple fields types like people picker, string, number, etc. And make the variables available in the flow and use it to contol the flow.
@NNusair You can acheive this by using Microsoft Forms. You can create a form then use the 'forms' trigger action in flow to get the answers and use them as variables in your flow. If you need more advanced option for the form you can create a PowerApp and then submit the responses to a flow from there.
