What's your point of showing the MCU cap? Captain America in the comics too has a degree of superhuman abilities

I like him being what he's described as (Superhuman)

I would like him to be borderline superhuman.

Low level superhuman

Well, it's not called Peak-Soldier Serum.

Both, in the sense that I think of "peak human" traits as those superlative human capabilities which are theoretically possible, but extremely unlikely for any human to have achieved by virtue of their genetic traits/environment alone. There are some that have speculated that superlative, peak human capability has been achieved in the category of speed by Usain Bolt. Since it is extremely unlikely that any human that has existed possesses many or all of these capabilities, one who does due to technological tampering with his body could be thought of as a "superhuman" specimen.

The superhuman aspect of Cap that I like to see, though, is not a set of peak human traits, but a peak human set of traits. Versatility, not off-the-charts performance in any one area (except maybe righteousness).
