My vanity and mirror are 90 inches long (giant length there-but due to vents only a phone booth for a shower-separate garden tub) We have 2 3-light fixtures, but we have 2 sinks and one is over each sink. The other bath is a 60, or maybe 66 inch and has a vanity bar that is 6 or 8 bulbs long. Based on that, I don't think a vanity bar is the way to go for your lenth. Get 2 fixtures and maybe leave equal space between them and on each end. Hopefully one lines up over the sink for you!

It's all about getting the heat of the ceiling when the furnace is not running. You should be running the fan in reverse, meaning it draws up the middle, hits the ceiling and blows down the walls. Do this at the lowest speed for a 12' ceiling in an average sized room.

Diana...Here is link to the 72"VANITY https://www.homedepot.com/p/SUDIO-Jasper-72-in-W-x-22-in-D-Bath-Vanity-in-White-with-Engineered-Stone-Vanity-Top-in-Carrara-White-with-White-Basin-Jasper-72W/314491746 Per your suggestion here is link to a black matte 24 x 36" oval mirror that I just found. https://www.homedepot.com/p/Umbra-Hub-24-in-H-x-36-in-W-Oval-Black-Modern-Mirror-1006044-040/30520501 I am thinking of keeping the vanity's included nickel hardware and adding matte black faucets. Do you think the mirrors 24" x 36" ( hung vertically above each sink) is a good proportion for the 72" vanity?

Actually, most ceiling fans (not huggers) are made to be installed on 8 foot high ceilings. It's only when a ceiling is lower than 8 feet that you need a hugger fan. As long as the blades are 12" or less from the ceiling it will be up to code. Here are some other important considerations: 1) Outdoor areas require more airflow than indoor areas because they are not confined spaces and the open air takes away from the intensity of the breeze since there are no walls for the air to bounce off. 2) When the blades of a fan are less than 12" from the ceiling, the amount of airflow it produces is reduced dramatically. Hugger fans may move as much as 30% to 50% less air than a fan that is hanging from a short rod where the blades are 12" from the ceiling. 3) It is better to use 2 smaller fans than one bigger fan, particularly outdoors. Smaller fans spin at a higher RPM and typically will produce a stronger breeze, but they produce that breeze in a smaller area, hence the need for two of them. So, two 52" to 60" fans is better than one 72" to 84" fan. 4) Don't just pick a fan by it's looks. Be sure to check out how much air it moves (CFM) and how fast it moves the air (Windspeed in MPH). The most important consideration is the wind speed because ceiling fans cool you off by creating a wind chill effect that is directly related to how fast the air flows, not how much air is moved. Larger fans move a larger volume of air, but at a lower speed. Even the best typical size fans (52" to 60") can only produce wind speeds close to 4 MPH. Lower end models may only produce 1 to 2 MPH. So look for fans as close to 4 MPH as possible. 5) Ceiling fans with the newer DC motors use about 75% less electricity and are typically better quality than the common AC motor fans.
