I think you are completely misremembering what the Apple product lineup looked like even with the Steve Jobs cleanup. At its absolute simplest, it contained the iMac, iBook, PowerMac and PowerBook lines. Within each line was a "Good", "Better" and "Best" pre-configured model each being a few hundred different from the other and each of those models was further configurable to add additional storage / memory etc.

That level of simplicity lasted from approximately 1999 to 2002 when the 14 inch iBooks, the 17 inch iMacs and the eMacs were introduced, followed by the 12 and 17 inch powerbooks in 2003. By 2005 they had also introduced the Mac Mini. And again most of these had a "good", "better", "best" variant, though in some cases (like the first 17 inch iMacs, the "best" tier was also the next model variant).

Apple's lineup is undeniably more complicated now than it has been in the past, but the simplification was never really about cutting model types down, so much as it was about making distinct model categories that people could easily understand why they would pick one or the other.

I think they still do a relatively good job at retaining that distinction, and I agree that the iPad lineup is probably the most muddled. Though special mention goes to the "Macbook Pro with M4 Pro" branding, which anyone should have caught and thought that maybe they needed a better moniker than "Pro" for the processor variant (and of course also, is the "Pro", the "Max" or the "Ultra" the best?)
