What other shades of blue are considered particularly noble, and what are their properties?
While this is a bit subjective, these shades of blue are notably noble. They've also got some impressive physical properties:

Navy Blue (#000080). Originally adopted as the dark blue color worn by officers of the Royal Navy of Great Britain beginning in 1748 (but back then it was called Marine Blue). Eventually the color was adopted by other countries' naval services and became known as Navy Blue. The color's association with nobility ties to peoples' positive connotations of military service.

Egyptian Blue (#1034A6). Believed to be the first synthetic pigment (with artifacts in this hue dated to circa 3250 BCE, during the Fourth Dynasty). Its long presence in the archaeological record has led researchers to believe the color was held in very high esteem among ancient Egyptian Civilizations. The actual pigment Egyptian Blue reflects infrared intensely under visible light (making it easy to spot), is luminescent in near-infrared light, can last for centuries, and delaminates by splitting into nanosheets after being immersed in water. These make it a potentially quite useful pigment for bioimaging, lasers, and security inks. Egyptian Blue absorbs light in the visible spectrum while reflecting infrared spectrum, which researchers believe could make it a valuable tool for cooling rooftops and building high-performance solar cells.

Admittedly, those properties apply to the Egyptian Blue chemical pigment; you probably can't just recreate those with the hex codes alone.
