If your gutting a vessel and modernizing the interior it's expensive and a lot of work. By design these older boats were not made for the lifestyle or components of today's new boats. There's only so much you can do with the old girls. They will never be like a modern boat.
In the competetive fishing world engines and running gear is far different from 40 years ago. Keeping an older hull relevant is tough and expensive. Especially when the 40 kt boats are in the mix.
For motoryachts the style and comforts have changed significantly. You just can't build a new interior and expect it to be like a new.boat when the structure and layout was never intended to be set up that way.
Most older hatts don't have large beds in the cabins. That's a big issue. My 41c has no way to make a proper master by today's standards without redesigning the deck and cabin. I'd love to have a queen or close to that size bed in the master. I'd also like a different galley layout and 2 heads but that's not an easy change.
I don't believe in the built in furniture being better or even useful. In fact I often don't find it comfortable either.
As far as the newer technologies and comforts go there's always good and bad. Just look at some of the newer vessels and see what you like and what you dont.

Funny to hear about modern interiors and the assumption that they are somehow better. A year or so ago, I had an owner of a new Fleming ask to come on my boat. He had owned a Hatteras in the past and wanted to see it. As he sat on the sofa, he says that he thinks he needs to sell his new Fleming and buy an old Hatteras. The reason: His wife hates the built in furniture. Says its just not as comfortable as the regular furniture they had in their previous Hatteras.
I never really thought about it before, but that built in stuff is usually just wood with a cushion on top. It probably isn't as comfortable as a sofa or chair with built in springs, etc.
my bunks are 6’4” half of these “modern” boats have bunks for midgets
