Airfare booking class, sub-class and perks

I saw Miles & More: What is a booking class?. While with my Qatar Airways experience I came to know that there are various sub-classes even within Qatar Airways and there isn't/wasn't any list which told which tickets are of which sub-class and what that entails. I'm talking about long-haul flights. I do understand that various airlines might view things differently but still it would be nice if there are some generic definitions that can be known.

The number of classes I have to come to know so far are -

a. Basic Economy - This is apparently a new class which has even more limitations than an Economy class.

b. Economy Class - This is what I flew , roughly 30kgs baggage allowance, between 16.5 to 18" seat of width and roughly 31 inches of seat pitch . Apparently there are number of sub-classes here by most airlines but what those are is unknown. Apparently some allow to pre-select your meals as well as seats while others do not. Qatar did.

c. Super Economy Class - Better legroom, seat pitch, probably better deal on baggage allowance - don't know anything more than that.

d. Business Class - Again a step up from from Super Economy class. Could be recliner seats to full-flat beds to suites (don't know what the term means). Amenity kits, toiletries, don't know what kind of food is served.

e. First Class - The ultimate in travel. Better options than Business Class. Premium amenity kits and premium food and wine service.

While seatguru does give some details of the kind of seating that most airlines offer (see comparison charts) they don't give the whole deal/scene. I'm not looking for specific airlines but to have a more generic outline of the possibilities.
