Just since you bought up the Toyota lineup, I can promise you that there's a vast difference, even between the Corolla and Camry, with the things you mentioned. More than I ever thought there'd be. I bought an '07 Corolla in '08, and really liked it. I liked the tight ride, the tight handling, and tossability, etc. Then an opportunity came up to buy a new '11 Camry for really cheap (thank you, recalls), and test drove one. I was hooked before I even left the dealer's parking lot on the test drive. NVH isn't even comparable. Ride smoothness isn't either. I thought I stepped out of a Corolla and into an Avalon or Lexus.
Obviously, there's a ton more space in the Camry, and it's easier for me to get comfortable in it. Even if objective leg/hip/head room is similar between a small car and a larger one, larger cars often have larger chairs and better chair padding. The structure is larger, so NVH seems to be inherently better. Wind noise isn't as loud in the Camry, and there's less wind buffeting on the road than in the Corolla (even though the Camry is still fairly light, at 3200 pounds).
To be sure, if you value a compact side and more direct input movements, smaller cars tend to deliver. If you value a more comfortable ride and more isolated environment, larger cars are probably your thing.
