New to this scene - help a guy out

[Robert Troub]

Hey friends. So, I’ve always like the simplicity of single speed bikes and anything without cables is a positive in my book. I have a few(!!) lightweights from the 50s through the 80s and I’m vaguely aware what is desirable in that area but post-war through around 1965 American middleweight and heavyweight (sorry if that is not the correct term) bikes are a new thing for me.
My basic question - is there a general hierarchy of brands from post war through ~1965? Yes, I know, there are always exceptions but is there a basic rule of thumb? In road bike world, any Huffy is barely worth lifting into a scrap bin. For example, is a Hiawatha better made than a Monark? I realize condition and complete is very significant but should I grab any Columbia (again, for example) left at the curb? I tend to think anything with a department store label is average quality or less. Am I wrong? I’m biased toward Schwinn since they have a track record of well designed and built stuff.
Any insight is appreciated

Thanks for the replies. I knew it would be a loaded question but a fellas gotta start somewhere.
I’m also assuming that stepthroughs and kids bikes generally don’t command premium $$. Correct?

Correct

Bike collecting is so personal; I really couldn't tell you what type of bike I collect...I just know it when I see it...all I know is that if its
cool and neglected I want to fix it and make it ridable again. I also like the bikes with a background or story...ex some Grampas bike that he bought new and all these years later I get to take care of his bike. to me that's priceless!
