Yeah, there is no right or wrong, just these different approaches to learn and lots of them work. I've experienced the same thing of wanting, in my head, to try all the approaches at once, sand, gravel, etc., but you kind of have to do each in its correct manner and just learn about that one and then perhaps have a different tank to try another one.
I made the same choice as you, to go with traditional gravel, in order to fully experience this thing about gravel-cleaning that I was trying to understand in a deeper way than I had years ago. It all sounds kind of simplistic now but I found it kind of awesome: The thing of always doing a gravel clean combines with doing water changes which combines with the whole thing of having a good biofilter and the three things together is much greater than the sum of these 3 maintenance items, its nothing short of amazing how beautifully this can maintain the water for tropical fish.
Its made me feel like finally I've proven to my own satisfaction that the simple gravel based "beginner" community tank is truly a viable environment, able to be maintained and run continuously with the fish being unhindered by "flaws" in the overall system. The 3 things just mesh together so powerfully: the gravel cleaning happening each week just never lets the debris and nitrates take over. The water change each week does a "reset" of the water chemistry by ridding the tank of all sorts of unknown organics and excess nitrates and brings in a fresh batch of calcium, magnesium and other things needed by the tank occupants. Meanwhile the biofilter constantly removes the two major toxins and can keep doing this forever if you do good filter maintenance. The filter itself assists with the debris removal and circulates the water, keeping the bacteria alive and helping oxygen exchange. Its sort of amazing how well it all works.
But that's only one avenue! You can do a similar sort of thing with sand and the gravel cleaning changes but the whole thing still works. You can do any of several approaches to a "planted tank" and a whole bunch of the processes you do are different skills to learn, some overlap, but definately different. Anyway, I guess those of us that for whatever reason can't have a lot of tanks (yet) just have to work on one thing at a time and just try to learn about and imagine the others!
