Stuff that works well in homes often is a lot more complicated to implement in restaurants, where you're: a) constantly fighting grease buildup and hard-to-remove dust that clings to greasy or damp surfaces, b) often have a profit margin of like 2% if you're one of the successful ones, c) aside from looking clean, you have to worry about pest control, fire codes, health codes (you can't have built-up dust falling in people's food, d) etc etc etc etc. Also, how restaurants look is as, or in some cases more important than the quality of the food. A good, attractive, practical restaurant design is one of the things that can steer you towards success or failure. Much to many chefs chagrin, hip and attractive restaurants with shitty boring food are often more profitable than ones that only focus on the food. Marketing is annoyingly important.

With, floors hardwood is a hard surface (so only mildly sound damping) so they're not too bad for cleaning and health stuff, but are expensive to install and take a lot to maintain if the worn-in look doesn't fit the aesthetic. Low-pile carpets can be shampood inexpensively for medium-term maintenance and replaced comparatively cheaply in the long run, but take a lot more effort to keep clean when someone drops a catering tray full of crème caramel and something with a port wine reduction.

Artwork: anything that you'd want hanging on your walls is either going to need to be a print or covered with glass or plastic because it will get ruined otherwise.

Acoustic panels are usually pretty ugly, difficult to clean, not resistant to pests, are a fire liability if coated in grease, etc.

Curtains definitely are definitely viable, but if you've got enough of them to really impact the sound level, they probably need to be expensive ones, and expensive curtains can't just be tossed in the wash and pressed on an ironing board.

It's not like they aren't effective, they're just not nearly as easy to deploy or maintain as they are in homes or offices.

Unrelated blathering because a lot of folks in tech don't have much exposure to this stuff and I always enjoy seeing a slice of someone else's life: In general a lot of people are understandably perplexed by seemingly simple, avoidable problems that they encounter in restaurants-- you can chalk almost all of them up to misinformation, or deliberately obfuscated factors. Firstly, there's a ton of inaccurate folk knowledge about the way restaurants work... (most infuriatingly to me is the food safety stuff. Look up the incubation time for most foodborne illnesses and consider how many people blame some lower GI symptoms the meal that met their stomach lining 3 hours earlier.) Also, a big part of the restaurant mystique is making it all seem sort of easy, uncomplicated, and fun, even for regulars and the 'friends and family' crowd; underneath that thin veneer, it's absolute insanity. I've worked in tech and the restaurant business extensively. Most days, the pressure level is "we just discovered a possible active intruder in our production systems" for at least a few hours. It's exhausting, and one of the reasons drug and alcohol addiction is so prevalent. Knowing that an entire staff is breaking their back so you can have a fun cozy bite to eat makes the experience palpably worse, but it's true. That's why you'll usually find people who've worked in the service industry are serious over-tippers. You have to give up a lot of your humanity to do that work, and a lot of people you encounter respect you less instead of more for having made that sacrifice.

I've proudly convinced so many people to not go into that business, though I've also convinced a few people to give it a shot. It's not a good choice for most people, but some people can't really do much else and be happy. In many ways, its especially tolerant to neurodivergent folks with different skillsets being downright useful in different roles. It's hard as hell though. There's a good reason that CIA (the school, not the spies) requires 6 months of full-time back-of-the-house restaurant work to get admitted to their degree program.
