Thanks, Duc. Yes, I noticed that after my initial post. Only the heads of families with princely or ducal rank (HSH/HH) are listed in the Belgian order of precedence, but ordinary members of the Belgian nobility (counts, barons, jonkheers, etc.) are not.
I was making a contrast with the UK where all peers, sons and daughters of peers, sons of sons of peers, baronets, knights, non-knight members of the orders of chilvary, and sons of baronets and knights are accorded some kind of precedence.

Spain used to be like the UK before the proclamation of the Second Republic. In the restored Spanish monarchy, however, under the royal decrees 2099/1983 and 470/2014, precedence is of course still accorded to the King and Queen, the Prince or Princess of Asturias, the Infantes
of Spain, the King emeritus and the Queen emerita, but no precedence is noted for children or spouses of infantes/infantas
, grandees of Spain and other non-grandee holders of titles of nobility, or knights of the orders of the Golden Fleece, Charles III, Isabella the Catholic, Alphonse X, Civil Merit, and so on.
Note that the latter are still distingushed by honorifics though. For example, children of infantes
, grandees of Spain (including their spouses and firstborns), and knights with collar or knights grand cross of the Spanish orders are Excelencia/ Excelentísimo(a) Señor(a).
Holders of titles of nobility without an attached grandeeship (including their spouses and firstborns) , members of the order of Charles III at any rank below Grand Cross, and commanders with star (roughly equivalent to Knight Commander in the UK) of any other Spanish order are Ilustrísimo(a) Señor(a)
. Still, it is a shame that they no longer have precedence in official events like their British counterparts.

Denmark, like the UK, also has a nicely structured order of precedence which includes, besides the Royal Family, former members of the Royal Family, illegitimate descendants of Kings, knights and commanders of the orders of the Elephant and Dannebrog, counts, barons, etc. , as it should be done in a proper, traditional monarchy.
