I agree with this approach. When I made the switch in late 2019 to Sony, starting from scratch with camera body and lenses, I started out with two lenses I knew I'd use no matter what -- two macro lenses -- and a fast mid-tele. As time went on I then added lenses as the need arose. It didn't take long to realize that, yes, I really needed a long zoom lens, and so I acquired one. Later on, several months later, I purchased a slightly shorter long zoom because I wanted something easier to handhold and carry on walks, and I'd found that the 200-600mm (the Bazooka) was just a bit too awkward and heavy to handle. For me, a slightly-built, petite and not exactly young woman, it's much more suited to using on the tripod with a gimbal.
Along the way, too, I wanted a couple more fast lenses and purchased an f/1.8 35mm and an f/1.8 85mm lens as well. I still need a lens wider than the 35mm and one of these days I'll finally get to actually buying it, but so far in my shooting I've managed without one, although there have been times when I've thought, "I've got to get a wide angle lens!" Basically, though, my lenses reflect the kind of shooting I do, so that each has its role in my photographic repertoire, although of course some lenses still see much more activity than others (that 90mm macro and the 100-400mm zoom have spent the most time on the camera to date).
And, yes, the best way to learn and determine what you really need (or would like) in the way of lenses is to shoot with what you already have.....
