I think the outdated look is the one where the entertainment center is too big for the room. When it overwhelms everything in the room and is the center of attention. That "look" is outdated but the actual entertainment centers are not IMO. Here are a couple pics of mine. It's huge. But the room is huge and is open to the kitchen and the ceiling is 18' tall so the room isn't overwhelmed by the furniture's mass. I've included a full view of my room just to illustrate that there are other more important things to look at in the room than just the entertainment center. That's my story and I'm stickin' to it!

I would take off the indent above the fireplace, replace the mantle with the same size piece of wood, and update the tiles. Gut the area where the TV is now and have a custom cabinet, flush with the fireplace wall, with an open shelve for the TV just a few inches lower than what it is now. Below the TV two wide drawers, one about 5 or 6 inches deep and the other about 11 or 12. Above the TV, two cupboards.

We are for sure doing away with the black trim! Lightening everything up! This house was added on to several times, which is why the layout isn’t what one would consider ideal. The wall with the large opening/thick black trim was actually an exterior wall at one point (the room in question didn’t exist then). At a point after that, the wall that will have the entertainment center was an exterior wall. Then they added the master suite onto that which is the doorway to the right of the entertainment center. I like the “open” concept with the large opening, but I also realize that comes to the detriment of easy furniture placement decisions. Only 2 doorways into the living room. One from the dining room, one from the master bedroom.

While I have nothing against Wayfair, it's not where I'd look for a significant focal point of your family room. In our area, having something custom built will mean a wait of at least a year and likely longer. There are also some big differences in quality of workmanship among the few custom furniture builders, and most focus on rustic looking pieces that would be at home in a fishing cabin. One retailer that may offer what you'd like is Room and Board. https://www.roomandboard.com/catalog/custom/cabinets https://www.roomandboard.com/catalog/living/media-cabinets Their custom pieces may still take 6 - 9 months while their other media cabinets may be available as soon as 3 months. Much of their furniture is made in PA, VT, NC and other US locations. In a lower price range, due to mostly being imports, are the contemporary media units offered by CB2. The store generally provides the Country of Origin in the product details. https://www.cb2.com/furniture/media-consoles/1?sortBy=priceHighToLow Good luck!
