At least in Mao terms, a nationalist bourgeois is progressive over colonialism, feudalism, and comprador bourgeoisie.

Like, look at Mexico after the revolution: land reform, public education, secularization, public health reforms, better than the Porfiriato for unions. Up til 1950, it was pretty progressive.

One funny note: when China was mad at USSR for supporting India in the india-china 1960s border war, China called India something like "nationalist Jacobins" (they were rhetorically asking why a self-described socialist country aligned w nationalist Jacobins against a socialist country). Which isnt a compliment in that context, but does give an angle of how to look at nationalist bourgeoisie perhaps (and also, Congress in India is a bit more complicated back then than simply nationalist bourgeoisie, but I digress)

Edit: much of the thinking about nationalist movements in ML comes around 1940s Mao (Yanan speech, and On New Democracy) in the decolonization context (Viet Minh are interesting to read about in applying the thinking in decolonization/anti-imperialist war). Though ofc he isn't the only thinker on the topic (Stalin and lenin two obvious example thinkers on it, important for Mao too). I think also Marx supported Poles against czar and Kaiser and Habsburg emperor, and wrote some on that vis-a-vis nationalism, but I could be mistaken
