Fonts that don't have regular and bold weights with default stretch get filtered out.
On Arch, I tried the package ttf-cascadia-code, and it only gives face info with regular (400) weight for 'Cascadia Mono PL'. However, the package otf-cascadia-code works perfectly.

It looks like ttf-cascadia-code is variable font and contains regular and bold weights. Isn't this sufficient? (Sorry if this is noob question)
@WatchMkr There is no variable font support in cosmic-text yet. When I did early explorations about this, I quickly hit a bug/limitation in rustybuzz (RazrFalcon/rustybuzz#91). So improved support in rustybuzz is required before this can be revisited.
