Have you done this before? Checked out any layouts online? Have you considered hiring a designer experienced in this area?

I have not done this before.... We have an architect that will be doing the patio cover design for the city permit.... but the design of the inside is what we want to situate

If your architect is not able to do so, you may need to find a landscape or outdoor kitchen designer who can.

Some or all of the utilities for this project may need to go under the patio. Make sure you have conduits in place for all utilities (water, gas, electric, phone, cableTV, & internet) before construction of the patio. And don't forget any pipe that might be needed for drainage.

thank you for this guidance. Do you know of a website where I can play around with the layout of the patio?

Your landscape architect will assist with the best design for your outdoor entertaining area. Some ideas for patios, fireplaces and outdoor kitchens from our website Photo Gallery:

A designer is going to be vital for this given the size of the spaces you described. You would be amazed at how quickly outdoor kitchens eat up floor space, and "fireplace" can be anything from a compact prefab unit to a massive, Game of Thrones-esque hunk of stone. It's not just about what fits, it's how usable is the space.
