You mean

           Family: Cascadia Mono
          Foundry: SAJA
            Width: normal
           Height: 105
           Weight: regular

right?  That is, the :weight 'semi-light attribute is not obeyed?  I 
observe the same behavior with Emacs 26-27-28, so at least it's not a 
regression.

Indeed.  A better way to do what you want is to move the :font attribute 
to the front:

(set-face-attribute 'default nil :font "Inconsolata LGC" :height 105 :weight 
'regular)

(set-face-attribute 'default nil :font "Cascadia Mono" :height 105 :weight 
'semi-light)

Likewise: move the :font attribute to the front and it will work.
